2. Voluntary change-of-mind position after delivery

Immediate digital supply or the start of a download will not be treated as waiving a mandatory consumer right. Subject to mandatory law and any more favourable Dodo remedy, Fermion's proposed voluntary policy may decline an ordinary preference-only request after successful delivery where the supplied file materially matches its description and samples. This is not a representation that downloading the file causes a statutory withdrawal or remedy right to expire.

A change of mind includes deciding that the subject, writing style, or difficulty level is not preferred after receiving a product that materially matches its description and sample.

3. Circumstances eligible for a remedy

A purchaser may request investigation and an appropriate remedy in the following circumstances:

  • the same order was charged more than once;
  • payment succeeded but the promised download or delivery instructions were not provided;
  • the product was delivered after the delivery schedule disclosed before payment, except to the extent that a force-majeure exception lawfully applies;
  • the delivered file is corrupted, unreadable, or cannot be opened in the compatibility conditions disclosed before payment;
  • the product is materially incomplete, defective, deficient, or materially different from the description or sample;
  • Dodo cancels or rescinds the resale transaction, or Fermion cannot supply the purchased product; or
  • applicable law otherwise requires repair, replacement, refund, compensation, or another remedy.

Depending on the circumstances and the purchaser's applicable rights, the remedy may be a working replacement file, completion or correction within a reasonable period, a full refund, a proportionate refund, or another remedy required by law. Fermion will investigate product defects, fulfilment failures, and the product-level remedy within its responsibility. Where a monetary refund is agreed or required, Fermion will promptly provide the relevant evidence and instruction or recommendation to the identified Dodo transaction seller, which will execute the transaction refund. Mandatory eligibility will not depend solely on a provider's discretionary approval.

4. How to request help or a refund

  • For a payment, duplicate-charge, invoice, transaction cancellation, or refund-status issue, use Dodo's charge and refund guidance page, which explains that the transaction-specific support email appears in the transaction email, or use the route shown in the receipt or the customer portal. The guidance page is not represented as a complaint-intake form.
  • For a missing, corrupt, materially misdescribed, or mathematically defective file, email contact@fermion.company with the subject "India product remedy request".
  • Include the Dodo order or payment reference, purchase email, product title, purchase date, and a concise description or screenshot of the issue.

Do not send a full card number, card security code, password, one-time code, or online-banking credential. We may ask for reasonable evidence needed to reproduce the issue but will not require information unrelated to the request.

5. Response and refund timing

Fermion will acknowledge a product complaint within 48 hours and aim to resolve it within one month of receipt. If a transaction refund is agreed or required, the identified Dodo transaction seller will execute it to the original payment method. Fermion will promptly provide relevant product and fulfilment evidence and will not treat a provider's voluntary-policy limit as reducing a mandatory remedy.

Posting time depends on Dodo, the payment method, and the buyer's bank. No refund-processing fee will be charged to the buyer unless a mandatory charge is clearly disclosed and lawful.

6. Dodo Payments resale and refund processing

If sales open, the exact Dodo entity identified at checkout and on the invoice will be the transaction seller and will execute transaction refunds under the confirmed reseller arrangement, applicable transaction documents, and mandatory law. Its current generic Buyer Terms do not yet identify that entity or resolve every remedy conflict. Fermion will be the product supplier and product-support provider, not the payment seller.

Fermion will cooperate promptly with Dodo and buyers on product-quality and fulfilment reports. A more favourable Dodo remedy or mandatory statutory remedy will not be reduced by this policy.

7. Refund amount and access after refund

A full refund covers the amount agreed by the responsible parties or required by mandatory law and is executed by the identified Dodo transaction seller. After a full refund, Dodo may revoke customer-portal or hosted-download entitlement and the product licence ends, subject to mandatory rights. A file already downloaded cannot necessarily be technically recalled, but further use must comply with the resulting licence status. Keeping a copy where necessary to pursue a legal claim is not restricted.

8. Statutory rights and escalation

This policy supplements and does not replace mandatory consumer rights. A purchaser may use the grievance redressal process and may approach an available consumer authority or forum if the matter is not resolved.

9. Conditions before sales

The proposed Dodo-hosted process is described in the digital delivery policy. Checkout will remain disabled until Dodo merchant and product approval, the exact transaction seller, India-facing responsibility allocation, final price and tax display, delivery, refund, and order-reconciliation gates are approved and tested.
