There are many reasons why a refund can get declined, but the most common one is when the cardholder's account is not capable of accepting the refund. Here are some of the most common reasons why refunds may be declined:

• Refunds are not supported by the card account: Some prepaid cards or debit cards may not support refunds, which can cause the refund to be declined. In such cases, the refund cannot be processed by the issuing bank, and the cardholder will need to find an alternative way to receive the funds.
• The card account was frozen due to fraud: If the bank detects fraudulent activity on the cardholder's account, they may freeze the account to prevent further fraudulent transactions. In such cases, the refund cannot be processed until the account is unfrozen and the bank verifies that the refund is legitimate.
• The cardholder closed the card account: If the cardholder closes their account before the refund is processed, the refund will be declined. In such cases, the cardholder will need to provide an alternative account or method to receive the refund.
• The cardholder has already disputed the transaction: If the cardholder has already disputed the transaction with their bank, the refund may be declined until the dispute is resolved. This can happen if the cardholder disputes the transaction as fraudulent or if they do not recognize the charge.

It is recommended to offer the cardholder to contact their card issuer to clear the situation out. The card issuer will be able to provide more information about the reason for the refund decline and suggest possible solutions. In some cases, the refund can be processed to an alternative account or method, such as a different card or bank account.
