Mastercard chargeback process

Understanding the Mastercard chargeback process

Written by Ayomikun

What is a Chargeback?

A chargeback is a report initiated by a cardholder when they dispute a credit or debit card charge.
​

Chargeback process

Grey ensures a structured and efficient process for handling card chargebacks. Below is the step-by-step guide:
​
​Dispute: The cardholder contacts Grey to dispute the transaction. To begin the process, you must provide the following:

  • A clear explanation of the issue.

  • Transaction details (date, amount, and merchant information).

  • Reason for the payment to the merchant.

  • Proof of engagement with the merchant.

  • Evidence that the merchant has refused a refund, and you did not receive value.

  • Any additional supporting documents that validate the claim.
    ​

Chargebacks have a nonrefundable processing fee of $40 per transaction. This fee will be deducted from your balance before initiating a chargeback.


​Chargeback initiation: We will review the claim and the provided evidence and initiate a chargeback against the merchant if the dispute is valid.
​

Investigation process: When a chargeback is initiated, we notify the merchant about the dispute. After completing the investigation, Grey will provide an update, which may result in either:

  • Approval of the chargeback – The transaction amount is refunded to the user's account.

  • Denial of the chargeback – If the transaction is found to be valid, the merchant confirming the transaction was successful, and the cardholder received value, the chargeback request will be rejected.
    ​

Timeframe for chargeback resolution

You can raise a chargeback or dispute within 30 to 120 days from the transaction or expected delivery date. The chargeback resolution will also take 30 to 120 days.

  • A refund is different from a chargeback— you must contact the merchant first for a refund.

  • A $40 non-refundable processing fee applies per chargeback and will be deducted from your balance before the chargeback commences.

  • Chargeback resolution takes 30 to 120 days.

  • Chargebacks cannot be filed after 30 to 120 days from the transaction date.
