1. Service
The seller is Trgovina, zanatstvo i usluge „CHIPTUNING“ Mladen Mitrović s.p. Banja Luka, JIB 4510823620007, VAT number 510823620007. The ATF Chiptuning portal offers credit packages and lets customers use credits to order digital file processing. Buying credits and ordering file processing are separate steps.
2. Customer account
Purchases require an approved account with accurate contact and billing details. Customers are responsible for protecting their login details and for the information and files they submit for processing.
3. Packages, prices and payment
Each package’s credit amount, price and currency are displayed before ordering. One credit costs 1 EUR excluding VAT. VAT of 17% is added. A 75-credit package has a net amount of 75.00 EUR, VAT of 12.75 EUR and a final price of 87.75 EUR. New packages and Monri card charges are in EUR. Earlier purchases, invoices and refunds retain their original amounts and currencies. Your bank may apply exchange rates and fees if your card uses a different currency. Ordered services are paid online using Mastercard®, Maestro® or Visa. There is no physical delivery charge. Check the amount and currency before confirming. Bank transfers, where offered, are confirmed after administrator verification.
4. Credit allocation and validity
Credits are added automatically after verified confirmation of successful card payment. Credits do not expire. Your purchase status and available balance are shown in your account. Returning from the payment page alone does not confirm payment.
5. Processing and digital delivery
The usual file processing time is 10–60 minutes. Completed files are delivered digitally through the corresponding portal request once processing is complete and that request’s payment requirements are met. No physical shipping is used. Contact support for the status of a particular request.
6. Unsuccessful processing and complaints
If a job cannot be completed successfully, the corresponding credit remains available for the next job. If credits were already deducted, they are returned to your account after the complaint is verified. Submit complaints through the portal or to info@atf-chiptuning.com with the request number or purchase reference and a description of the issue. Support reviews the matter and informs you of the resolution. This provision covers credit availability after an unsuccessful job and does not exclude customer rights under mandatory applicable law.
7. Cancellation before payment
You may cancel your purchase before confirming payment. Closing the Monri form alone does not confirm that no charge occurred. If you have already been charged or the status is unclear, check your purchase history and contact support with the purchase reference before paying again.
8. Refunds for unused credits
You may request a refund for purchased, unused credits without giving a reason within 15 calendar days of buying the package. We offer this policy to all portal customers. For a wholly unused package, we refund the full amount paid, including VAT paid. For a partially used package, we refund the proportional original amount paid for the remaining unused credits, including the corresponding VAT paid. Refunds use the price of that purchase, rounded to two decimal places, rather than any later price list. Total refunds cannot exceed that payment. Used credits and service complaints are addressed below.
9. Submitting a request
Send a written request to info@atf-chiptuning.com or through portal support. Include your account email, purchase reference or invoice number, and the number of unused credits you want refunded. No reason is required for withdrawal within the stated period; for a service complaint, describe the issue and include the file processing request number. Support checks the payment and credit usage. Please do not spend the credits you are requesting to refund while the request is being reviewed. Never send your full card number, CVV, PIN or one-time security codes.
10. Response and refund deadlines
Support sends an initial response within two working days of receiving your request. For this deadline, working days are Monday–Friday excluding public holidays. Refunds for timely withdrawal are made without undue delay and no later than 15 calendar days after we receive the written withdrawal notice. For other complaints, our initial response explains the next step and expected resolution time, subject to mandatory statutory deadlines. We email confirmation after the refund is processed. The time it takes to appear on your card account also depends on the issuing bank.
11. Refund method and credit balance
Card refunds are processed manually through Monri to the same card used for the purchase, in the original transaction currency. We charge no refund processing fee. If your card has expired or the account is closed, contact support so we can check the procedure with Monri and the bank. For bank transfers, where offered, refunds go to the original payer’s account. After a confirmed refund, the corresponding credits are removed from the balance and the customer receives a refund record and the appropriate accounting document. The same credits cannot remain available for use and also be refunded in money.
12. Unsuccessful processing, complaints and customer rights
If a job cannot be completed successfully, the corresponding credits remain available for the next job or, after the complaint is verified, are restored if already deducted. Customers may also request a monetary refund where entitled; retaining credits is not a compulsory replacement for such a refund. Complaints about completed processing are reviewed according to the issue and resolved in accordance with customer rights. Report incorrect or duplicate charges as soon as you become aware of them. The 15-day unused-credit refund period does not limit rights concerning an unperformed or defective service, incorrect charges or other rights under mandatory applicable law. Credits do not expire after that period; contact support for individual review of other refund requests.
13. Security and privacy
Card details are entered on Monri’s page. The portal does not collect or store your full card number or CVV. Information required to process the payment is sent to Monri: name, contact details, billing address, order reference, amount and currency. The portal retains purchase and payment confirmation records to allocate credits and maintain transaction records. A PDF invoice for confirmed payment is sent to your account email. Processing purposes, recipients, retention criteria and user rights are described in the separate portal privacy policy linked below. Accepting these terms is not marketing consent. For personal data enquiries, contact info@atf-chiptuning.com.
