If there is a refund transaction with the CCB credit card, it will be refunded directly to the credit card

At the same time, the refund after the refund will be counted as repayment (the transaction is canceled on the same day, Partial installment returns are not counted). After the money is returned to the card, it will be deducted from the poster’s bills first. After the deduction is completed, it will be deducted from the bills that have not been issued. If there is more, it can be used to offset the poster’s future transactions (not for a certain transaction)

For enquiries, you can check their official website. There is an "Account Inquiry Service" on the left, select "Credit Card Inquiry", and after entering the information as required, you can view the issued and unissued bills. For details, the words "date" or "refund" or "return" will often appear in the details of the return transaction.

If the poster has any other questions, you can ask.
