Root Cause

• Chargeback already processed: The payment has been reversed through a chargeback initiated by the customer, making it ineligible for further refunds.

• Refund attempted after chargeback completion: A refund request was made for a transaction that has already been settled via a chargeback.

• Processor restrictions on duplicate refund actions: The payment gateway blocks refund attempts once a chargeback has been finalized to avoid duplicate reversals.

Troubleshooting and Solutions

• Inform the customer that a chargeback has already been processed for the transaction, and no additional refund can be issued.

• We recommend that the customer contact their bank or card issuer for any further clarification regarding the chargeback.

• Review internal records to confirm that no additional refund attempts are made on this transaction.

• Educate the customer on the difference between refunds and chargebacks to prevent confusion in future transactions.

• Implement clear communication and prompt issue resolution to help prevent customers from initiating chargebacks.
