Section 1 — Scope of this Policy and Relationship to the WERT Terms & Conditions of Service

1.1 This Policy applies to every service WERT provides (including liquid-injection termite treatment, pipe-based termite treatment systems, the termite baiting system, general pest control, and commercial-premises services) within our service areas of Chonburi and Rayong provinces, however you place your order (LINE, telephone, in person, the website, or any online channel once available).

1.2 This Policy forms part of the WERT Terms & Conditions of Service. On the subjects of cancellation, rescheduling, refunds, and payment disputes, this Policy is the specific document and takes precedence.

1.3 The quotation and service contract for a particular job may set job-specific details (such as the number of service visits, warranty period, and covered area). Those documents are to be read together with this Policy; where they differ on job-specific figures or scope, the job documents prevail, unless that would leave you with less protection than the law requires. For consumers, a job-specific document may reduce a protection stated in this published Policy only where the difference is specifically highlighted, separately signed or accepted, and justified by the nature of that job; otherwise this published Policy prevails.

1.4 Nothing in this Policy is intended to limit or exclude any right you have under law, including the Civil and Commercial Code, the Consumer Protection Act B.E. 2522 (1979), the Unfair Contract Terms Act B.E. 2540 (1997), and — where it applies — the Direct Sales and Direct Marketing Act B.E. 2545 (2002). If any provision conflicts with mandatory law, it is ineffective only to the extent of the conflict, and the remainder of this Policy continues in force.

1.5 This Policy is issued in Thai and in English with identical substance. To the extent permitted by applicable law, the Thai version prevails in the event of any difference in interpretation.

Section 2 — Definitions and the Eight Distinct Payment Matters

To resolve matters quickly and through the right channel, WERT distinguishes eight types of payment-related matters, each with its own process and legal consequences:

2.1 WERT-approved Refund — WERT agrees to return all or part of your payment under this Policy, your contract, or the law, through the original payment channel (Section 9).

2.2 Customer Cancellation — you cancel all or part of a service you have ordered. The outcome depends on the stage the work has reached when you notify us (Section 3).

2.3 Rescheduling — changing the service date or time while the job itself continues. It is not a cancellation and, as a rule, involves no refund (Section 4).

2.4 Payment Dispute — you notify WERT directly that a charge, amount, or payment record is incorrect, so that WERT can investigate and put it right (Sections 11 and 13).

2.5 Chargeback through your card issuer — the process by which you exercise rights through your bank or card issuer under the card networks' rules (e.g., Visa, Mastercard). It is a separate track from requesting a refund from WERT (Section 11).

2.6 Unauthorized / Fraudulent Transaction — a payment made without the authorization of the cardholder or account holder, such as where a card is stolen or card details are compromised (Section 12).

2.7 Duplicate Payment — more than one payment for the same item, such as a repeated transfer or a card charged twice (Section 7.1).

2.8 WERT Unable to Provide Service — WERT itself cannot deliver the agreed service, for example because the property is outside our service area or we cannot field a crew (Section 7.3).

2.9 Payment status is not appointment status. "Payment received" means only that WERT has received your money. It does not mean "service appointment confirmed." An appointment is confirmed only when WERT expressly confirms the service date and time to you (for example via LINE, an appointment document, or the WERT member system). Wherever this Policy refers to "appointment confirmation," time runs from that express confirmation.

2.10 "Actual costs" in this Policy means costs that (a) have genuinely been incurred specifically for your job, (b) WERT can prove with evidence such as receipts, purchase orders, or materials-issue records, (c) cannot reasonably be recovered or redeployed to other work, and (d) are attributable solely to the cancelled or undelivered portion of the services. Costs of work already delivered are treated as included in the value of the delivered work that WERT is entitled to retain, and are never deducted a second time. Whenever any cost is deducted from a refund, WERT will provide you with an itemized statement and the supporting evidence.

Section 3 — Service Stages (A–F) and the Effect of Customer Cancellation at Each Stage

The Direct Sales and Direct Marketing Act takes precedence over this Section: for purchases within the scope of the Direct Sales and Direct Marketing Act B.E. 2545 (2002) (for example, orders placed and paid online, where that Act applies to the purchase), cancellation within 7 days of receiving the service follows Section 8 — a full refund within 15 days — and the stage deductions in this Section do not apply, except for any set-off the law permits.

3.1 Stage table

Table note: this table is subject to Section 8 — a lawful cancellation within 7 days under the Direct Sales and Direct Marketing Act B.E. 2545 receives a full refund within 15 days, without the Stage C–F deductions, except for any set-off the law permits.

3.2 Rules by stage

(a) Stage A — before the service date is confirmed: you may cancel at any time. WERT refunds everything received, with no deduction whatsoever.

(b) Stage B — appointment confirmed, no preparations yet: you may cancel, and WERT refunds in full. Giving notice within the advance-notice window in Section 3.3 is the best way to ensure your job is still at Stage B (no costs yet incurred).

(c) Stage C — genuine preparation costs incurred: WERT refunds after deducting only actual, provable, unrecoverable costs as defined in Section 2.10. The burden of producing evidence of those costs rests on WERT.

(d) Stage D — crew already en route: in addition to the costs under (c), WERT may charge a travel/call-out fee at a reasonable rate consistent with the loss actually suffered (under the rules in Section 4.3). WERT acknowledges that a court may reduce any excessive agreed charge under Section 383 of the Civil and Commercial Code, and intends to set the rate close to true cost from the outset. Travel and dispatch costs are charged only under this call-out head and are never also counted as costs under Section 2.10.

(e) Stage E — service begun: even after service has begun, you retain your statutory right to terminate the remaining work (Civil and Commercial Code, Section 605), while WERT is entitled to the value of the work already performed (Section 391 paragraph 3). The value of work performed is calculated at the rate of the package/contract you actually bought — not re-priced retrospectively at single-visit rates. For annual packages see Section 5; for the baiting system see Section 6. The only deductible costs are Section 2.10 costs attributable to the cancelled/undelivered portion — costs of the work already delivered are treated as included in the value of the delivered work WERT is entitled to retain, and are never deducted a second time.

(f) Stage F — work fully completed: there is no cancellation or refund for change of mind after completion. However, the following remain fully intact: (1) your statutory claims for defective work, (2) your rights under the warranty stated in the quotation/contract for that job, and (3) any statutory termination right that applies (see Section 8). If there is a problem with the work, please contact WERT first so we can inspect and remedy it under the warranty terms.

3.3 Minimum advance notice for cancellation/rescheduling. To cancel or reschedule free of charge, please notify WERT through the channels in Section 13.1 before the appointment time, as follows: (a) general service visits (such as soil injection, spraying, or installation work): at least 48 hours before the appointment time; (b) follow-up/refill visits under the baiting system: at least 24 hours before the appointment time; (c) Fairness carve-out: in cases of force majeure, medical emergency, or other events beyond your control, WERT charges nothing even where notice is shorter than the above; (d) late notice never forfeits your refund as a whole — its only effect is the deduction of actual costs under Stages C–E of this Section.

3.4 Evidence and calculation: whenever any amount is deducted, WERT will state the refund amount, the calculation method, and the cost evidence in writing (on paper or electronically) before processing the refund.

3.5 Deposits: where your job involves a deposit, any forfeiture or deduction from the deposit is limited to the loss actually suffered, applying the principles of Section 3.2 together with Section 7 of the Unfair Contract Terms Act B.E. 2540. WERT does not operate an "automatic deposit forfeiture" policy.

Section 4 — Rescheduling, and Cases Where the Crew Cannot Gain Access (No-show / No-access)

4.1 Rescheduling by the customer: notify us through any channel in Section 13.1. If you give at least the advance notice set under Section 3.3, rescheduling is free of charge and may be done within reason, without a fixed limit on the number of times. If notice is shorter and WERT has already genuinely incurred costs, the principles of Stages C–D in Section 3 apply with the necessary changes.

4.2 Rescheduling by WERT: if WERT must reschedule (for example, weather unsuitable for soil injection, safety concerns, or crew/materials disruption), WERT will notify you as early as possible and propose a new date, at no cost to you. If repeated rescheduling by WERT leads you to no longer want the service, you may cancel and receive a refund according to the stage the job has reached (work not yet begun is treated as Stage A/B — refunded in full).

4.3 Crew arrived but could not perform the service (no-show / no-access): this covers cases where the crew arrives at the agreed time, but no one provides access, you cannot be reached, or the premises are not in a workable condition — without prior notice to us.

In such cases: (a) First incident: WERT will re-book one new appointment at no charge. (b) Subsequent incidents: if the same situation recurs, WERT may charge a travel/call-out fee equal to the actual, documented cost of that dispatch (such as fuel and crew working hours taken from actual records), and will provide you with the itemized calculation and evidence required by Section 3.4 before charging. (c) Travel/call-out costs are charged only under this Section 4.3 and are never also counted as costs under Section 2.10.

4.4 Counting of service rounds on no-access (baiting-system jobs). For follow-up/refill visits under the baiting system, a service round is treated as delivered once the coordinated and confirmed appointments for that round have failed for the reasons described in Section 4.3 two (2) consecutive times. Before that rule starts to count, WERT will warn you in writing after the first failed appointment, stating that if the next coordinated appointment also fails consecutively, that service round will be treated as delivered. This rule applies together with Section 6.3 and is the rule referred to by Section 8.2 of the WERT Terms & Conditions of Service.

4.5 Access for baiting-system follow-up visits: Section 6.3 applies additionally to baiting-system jobs.

4.6 Rescheduling does not affect amounts already paid and does not of itself create a refund entitlement; the job simply continues at its stage under Section 3.

Section 5 — Mid-term Cancellation of Annual Service Packages

5.1 Annual packages (such as WERT Standard / Pro / Pro Max, comprising soil injection and the spray/follow-up visits stated in your quotation and contract) are continuing service contracts. You may terminate before the end of the term as the law allows, and WERT will calculate your refund fairly from the following factors: (a) services actually rendered (the injection work and any spray/follow-up visits already performed); (b) the value of services rendered, priced at the rate of the package you actually bought (the price actually paid, after discounts) — never re-priced retrospectively at single-visit walk-in rates; (c) materials/chemicals purchased or prepared specifically for the undelivered portion of the services that cannot be recovered or redeployed (materials/chemicals already consumed on services delivered are treated as included in the value under (b) and are not deducted again); (d) actual costs as defined in Section 2.10 attributable to the cancelled/undelivered portion only; and (e) the undelivered portion of the services, which is the portion to be refunded to you.

5.2 WERT does not operate a "no refunds on annual packages under any circumstances" policy — a term of that kind is inconsistent with fairness principles under Thai law and is not WERT's approach.

5.3 Refund calculation rules:

(a) Primary rule — component-weighted formula: where your quotation breaks the package price into component values before the sale (for example, soil-injection work = THB X; each spray/follow-up visit = THB Y; totalling the package price), Refund = price actually paid − value of components already delivered − actual costs under Section 2.10 attributable to the undelivered portion only (costs of delivered components are treated as included in those components' value and are never deducted again).

(b) Mandatory conditions of the primary rule: (1) the primary rule applies only where the component-value breakdown appeared in your own quotation before the sale or in the service contract you signed; (2) the first-visit component (the soil-injection work) must not exceed documented direct cost plus a stated reasonable margin, supported by a cost file WERT keeps ready to produce as evidence; and (3) WERT reviews the component weights against actual costs periodically.

(c) Automatic fallback rule — per-visit average formula: where neither your quotation nor the service contract you signed shows a component-value breakdown, the per-visit average formula applies automatically (not at WERT's option): Refund = price actually paid × (visits not yet received ÷ total contracted visits) − actual costs under Section 2.10 attributable to the undelivered portion only.

(d) In every case, the calculation remains within the frame of "the value of the work already performed" under Section 391 paragraph 3 of the Civil and Commercial Code, and WERT acknowledges that a court may reduce any excessive amount under Section 383. WERT will show you the calculation method and evidence in accordance with Section 3.4 in every case.

5.4 Promotional/discounted packages: every formula uses the price you actually paid, not the undiscounted list price.

5.5 Notice of termination under this Section may be given through any channel in Section 13.1. The value of work delivered is measured up to the date WERT receives your notice. Any warranty attached to the package ends in accordance with the contract terms for that job upon termination, without affecting your statutory claims for defects in the work already performed.

Section 6 — Special Terms: Termite Baiting System

6.1 Station installation is commencement of service. A baiting-system job is a continuing program consisting of installing bait stations and follow-up/refill visits in the number and cadence stated in the quotation and contract for that job. Once WERT has installed the stations and placed bait, service has commenced (the job immediately enters Stage E under Section 3).

6.2 Deductible costs on baiting-system jobs. Bait, chemicals, and consumables that WERT has purchased or prepared specifically for follow-up/refill visits not yet performed, and that cannot reasonably be recovered or redeployed, are actual costs under Section 2.10 and may be deducted from any refund. Bait, materials, and installation labor for the portion of the work already delivered (such as installing the stations and placing bait) form part of the value of the delivered work that WERT is entitled to retain under Section 6.4, and are never deducted a second time.

6.3 Duty to allow access for follow-up visits. The baiting system's effectiveness depends on continuous scheduled inspection and refilling. You agree to give the crew access at the agreed follow-up times. If access is refused, appointments are repeatedly postponed beyond a reasonable interval, or stations are moved, opened, or destroyed without WERT's agreement, the program may not perform as designed and warranty outcomes may be affected in accordance with the contract terms for that job. Before any warranty consequence takes effect, WERT will give you at least one written warning identifying the consequence, together with a reasonable period to re-book or remedy the situation before that consequence applies. The counting of service rounds on no-access follows Section 4.4 — once two (2) consecutive coordinated and confirmed follow-up appointments fail for reasons on your side, that service round is treated as delivered, with WERT warning you in writing before that rule starts to count, as set out in Section 4.4.

6.4 Cancellation after installation. If you cancel the program after stations are installed, WERT will refund only the value of the undelivered portion of the program (follow-up/refill visits not yet performed, at the values stated in — or fairly averaged from — the quotation and contract), less actual costs under Section 6.2. Costs of the work already delivered are treated as included in the value of the delivered work WERT is entitled to retain, and are never deducted a second time. WERT will provide the itemized calculation and evidence required by Section 3.4.

6.5 Ownership of bait stations, and collection on cancellation or completion. Bait stations and equipment installed by WERT remain WERT's property. When the program ends — whether by cancellation or on completion of service — WERT will schedule a visit to collect the stations and equipment at no extra charge to you. Station collection is part of job close-out, consistent with an operator's duty of care over hazardous substances and chemical-bearing equipment. You agree to give WERT access for that collection visit.

6.6 Baiting-system warranty. The warranty period and scope (including any continued warranty after the final visit, as published) are as stated in the quotation and contract for that job. A warranty conditioned on completing the program does not arise where the program is cancelled before completion under Section 6.4. This does not affect your statutory claims in respect of the services already delivered.

Section 7 — Cases in Which WERT Refunds

WERT will refund, by the method in Section 9, in the following cases:

7.1 Duplicate payment: once verified, WERT promptly refunds the duplicated amount in full, with no deduction.

7.2 Incorrect amount charged: if the amount collected exceeds the amount agreed in the quotation/contract, WERT promptly refunds the difference in full.

7.3 WERT cannot provide the service and nothing has been delivered: for example, the property is outside our service area, we cannot field a crew or source materials, or a site survey shows the agreed work cannot be performed — full refund of everything received. WERT will normally contact you to confirm an appointment within 2 business days of receiving your payment; and if WERT has not confirmed an appointment within 14 calendar days of your payment, you may immediately choose between a firm service date and a full refund by notifying WERT through the channels in Section 13.1 — WERT's normal practice is also to contact you to offer that choice (mirroring Section 4.3 of the WERT Terms & Conditions of Service).

7.4 Mutually agreed cancellation: refund in the amount and on the terms agreed in writing.

7.5 Refunds required by law: including exercise of the 7-day statutory cancellation right under Section 8 (Direct Sales and Direct Marketing Act B.E. 2545) and any other case in which the law requires WERT to refund — statutory rights that this Policy does not displace.

7.6 Other cases WERT approves: WERT may refund in special cases as a matter of customer care. Case-by-case approval does not create a binding precedent for other cases.

Section 8 — 7-Day Statutory Cancellation Right for Purchases under the Direct Sales and Direct Marketing Act

8.1 Where your purchase falls under the Direct Sales and Direct Marketing Act B.E. 2545 (2002) (for example, orders placed and paid through the online channel once available, including payment via a personal payment link, where that Act applies to the purchase), you may cancel the contract by written notice within 7 days of receiving the service, under Section 33 of that Act. This is a statutory right that this Policy does not displace, limit, or make subject to any additional condition.

8.2 How to exercise the right: give written notice of cancellation through the channels in Section 13.1 (email contact@wert.in.th or LINE Official: @WERT is recommended, so the notice date is clear), stating your name, the order/receipt number, and the payment date. The refund deadline runs from the date WERT receives your cancellation notice.

8.3 Refund deadline: WERT will refund within 15 days of receiving your cancellation notice, as required by Section 36 of that Act.

8.4 Relationship to Section 3: the stage deductions (A–F) in Section 3 do not apply to a lawful cancellation under this Section, except for any set-off the law permits.

Section 9 — Refund Method

9.1 Original payment channel (wherever possible): (a) Paid by card → refunded only to the same card used to pay, through the payment service provider / card network (card payments are not refunded in cash or by transfer, as that would breach card-network rules and anti-money-laundering standards). A card refund is always submitted to the original card, even if that card has since been closed or replaced — the issuing bank normally redirects the funds to your new card or account; if that fails, Section 9.1(d) applies. (b) Paid by bank transfer → refunded to the originating account, with the account name verified against the payer. (c) Paid in cash → refunded by transfer to a bank account in the payer's name, with identity verification and a signed refund acknowledgment. (d) For bank-transfer and cash payments: if the original account genuinely no longer exists (e.g., it has been closed), WERT will refund to another verified account in the same person's name and document the reason. For card payments: WERT will refund by transfer to a verified account in the cardholder's name only where the payment service provider confirms in writing that a credit to the original card can no longer be processed (for example, because the refund window for the original transaction has lapsed), and WERT retains that confirmation as evidence.

9.2 WERT's responsibility is for the THB amount. WERT is responsible for refunding the approved Thai Baht (THB) amount in full and does not deduct payment-processing fees from the approved amount. Exchange-rate differences and card-issuer fees are a matter between you and your issuer, as described in Section 10.

9.3 Timing. Once a refund is approved, WERT will submit the refund instruction to the bank or payment service provider within the time set under Section 13.3. After the instruction is submitted, the time for funds to reach you depends on the payment service provider, the card network, and your issuing bank, and is outside WERT's control (card refunds commonly take about 5–10 business days to appear on a card account — general information, not a commitment). WERT will provide refund reference evidence (such as the transaction reference number) on request.

9.4 Where the law prescribes a specific refund deadline (such as the 15 days under Section 8), the statutory deadline governs.

Section 10 — Foreign-issued Cards and Currency Conversion

10.1 WERT prices and charges in Thai Baht (THB) only and does not offer point-of-sale currency conversion (no Dynamic Currency Conversion). The amount shown on your statement in your own currency results from conversion by the card network and your issuing bank at the issuer's rates and policies, which may include a foreign transaction fee and a currency-conversion fee set by your issuer.

10.2 Card refunds are made in THB, in the approved amount, to the same card. Your issuing bank converts the refund to your currency at the exchange rate on the refund processing date, which may differ from the rate on the payment date. The amount you receive back in your own currency may therefore be more or less than the amount originally billed, and issuer fees may or may not be returned under your issuer's own policy. These differences are not a defect in the refund and are not WERT's responsibility.

10.3 Illustration (all figures hypothetical, for explanation only): you pay THB 20,000 with a card issued in the United States. • On the payment date, at an assumed rate of THB 36.00 per USD, your issuer bills approximately USD 555.56, possibly plus a foreign transaction fee (e.g., at 2%, approximately USD 11.11), for a total of approximately USD 566.67. • WERT later refunds the full THB 20,000. If the rate on the refund processing date is THB 37.00 per USD, you receive back approximately USD 540.54; if the rate is THB 35.00 per USD, you receive back approximately USD 571.43. • Any fee your issuer originally charged may or may not be returned, under the issuer's own policy. In every case, WERT's refund is complete when the full approved THB amount — THB 20,000 — has been refunded.

10.4 For questions about exchange rates or card fees, please contact your issuing bank, which alone sets those rates and policies.

Section 11 — Payment Disputes and Chargebacks

11.1 Contact WERT first. If you see a charge that looks wrong or unfamiliar, or you are dissatisfied with the service, you agree to contact WERT through the channels in Section 13.1 and allow WERT 7 days to investigate and resolve the issue before initiating a dispute with your bank or card issuer. Nothing in this agreement limits your statutory rights or your rights under the card networks' rules (see Section 11.2). Most issues (wrong amounts, duplicates, an unrecognized merchant descriptor on your statement, defects in the work) can be checked and put right far faster than a bank process.

11.2 Your rights remain intact. The contact-first commitment in Section 11.1 exists for speed of resolution only. Nothing in this Policy removes or limits your statutory rights or your right to dispute a transaction through your card issuer under the card networks' rules.

11.3 A chargeback is not a WERT refund. A chargeback runs between the issuing bank, the card network, and the payment service provider, on their own timelines. Filing a chargeback while WERT is already processing your refund can delay your money. Where WERT has already refunded, you will receive reference evidence you can give your bank immediately. Once a chargeback has been filed with your issuer, WERT is required to suspend any pending refund and respond through the card network's dispute process instead; the outcome is then determined by that process.

11.4 WERT's right to respond with evidence. When a chargeback is filed, WERT is entitled to present the facts to the bank and card network through its payment service provider, submitting relevant evidence to the extent the law allows, which may include: the quotation; the invoice/receipt; payment confirmation; the IP address and device data recorded when the order was placed or the terms accepted; the timestamp and version of the terms accepted; the service address; appointment records and confirmations; message correspondence (e.g., LINE/email); site photographs; service reports; evidence of site attendance including location (GPS) data to the extent the law allows; signatures and handover documents; before-and-after photographs; and follow-up visit records. Collection and use of this data is governed by WERT's Privacy Policy (on the bases of contractual performance and legitimate interests in establishing and defending legal claims).

11.5 Claims of "unrecognized transaction" where the service was received. Where the evidence shows that the service was ordered, received, and confirmed as satisfactory, but a chargeback is later filed claiming the transaction was unrecognized or unauthorized, WERT will fully exercise its right to contest that dispute with the evidence described in Section 11.4. Only where a chargeback is filed fraudulently or in bad faith, with knowledge that the charge was proper, and causes WERT loss, does WERT reserve the right to claim the damages actually suffered, only as far as Thai law permits and only through lawful process — WERT imposes no flat "chargeback penalty" on customers.

11.6 WERT handles every dispute professionally and without prejudice, and will refund promptly whenever the facts show you are entitled to a refund under this Policy or the law.

Section 12 — Unauthorized or Fraudulent Transactions

12.1 If you find a charge from WERT that you did not make (for example, your card or account was used by someone else): (a) contact your bank or card issuer immediately to block or suspend the card; and (b) notify WERT through the channels in Section 13.1 with whatever transaction details you have, so WERT can investigate and place any related service on hold.

12.2 How WERT treats genuine fraud victims. WERT will investigate promptly, suspend any service not yet delivered, cooperate fully with the issuing bank, the payment service provider, and law-enforcement officials, and — where it verifies that a transaction was fraudulent and no service has been delivered — will refund/void the transaction on WERT's side without waiting for other processes to conclude. You may also report the matter to the police, and in Thailand to the Anti-Online-Scam Operation Center (AOC hotline 1441).

12.3 WERT-side safeguards. To prevent fraud, WERT reserves the right to verify identity or card authorization for transactions showing unusual characteristics, to pause commencement of work during verification, and to refund and decline orders reasonably believed to be unlawful, notifying the payer in each case.

Section 13 — How to Request a Refund

13.1 Channels: LINE Official: @WERT · Email contact@wert.in.th · Tel. +66 81 968 2294. All channels are equally valid; a written channel is recommended so the notice date is clear.

13.2 Information to include: your full name and contact number · quotation/contract/receipt number (if available) · payment date and amount · payment channel with evidence (e.g., transfer slip, or the last four digits of the card — never send a full card number or CVV) · the reason for the request · for transfers: the original destination account for receiving the refund.

13.3 Process and normal timelines (items (4) and (5) are binding deadlines in every case): (1) WERT normally acknowledges the request within 2 business days of receiving it; (2) WERT normally notifies its decision, with the amount and the calculation method, within 5 days of receiving complete information; if WERT needs further information, it will request it promptly, aiming to cover everything in one request; (3) once approved, WERT normally submits the refund instruction to the bank or payment service provider within 2 days of approval, and never later than any statutory deadline; (4) Hard backstop for card payments: in every case where a refund is approved or a cancellation is accepted, WERT submits the card credit no later than 14 calendar days after receiving the cancellation/refund request, regardless of internal process stage; (5) Statutory path — 7-day cancellation under the Direct Sales and Direct Marketing Act B.E. 2545 (Section 8): WERT refunds within 15 days of receiving the written cancellation notice, independently of every other timeline in this Section.

13.4 The decision: WERT gives its decision in writing. If costs are deducted, the itemization and evidence required by Section 3.4 are attached. If the request is declined, WERT states the reasons and the contractual/legal grounds relied on.

13.5 If you disagree: you may ask for one further review with additional reasons. This does not affect your right to complain to the Office of the Consumer Protection Board (OCPB hotline 1166), to bring proceedings under the Consumer Case Procedure Act B.E. 2551 (2008), or to dispute the transaction through your card issuer.

Section 14 — Policy Versions and Which Version Applies

14.1 This Policy always displays its version number and effective date in the header. WERT retains every historical version, and you may request a copy of any earlier version through the channels in Section 13.1.

14.2 The version that applies to your transaction is the version in force at the time you paid for that transaction. Later amendments do not apply retroactively to payments already made, unless the amendment gives you greater rights.

14.3 When WERT opens online payment, the checkout will present this Policy (or a summary with a link) at the payment step before you confirm, and will record the policy version, the date and time, and your acceptance as part of the transaction record. The same applies to payment via a personal payment link WERT sends to you: the link always opens WERT's payment-confirmation page before proceeding to payment.

14.4 Material amendments will be announced on wert.in.th with their effective date. Amendments affecting contracts still within their term will be announced at least 30 days before they take effect, and an amendment that reduces your rights will not apply to that contract until its next renewal.
