The first one is that if you pay by credit card, the refund after return is the classification of the bank card you used when paying, and you choose the refund method. In this case, the credit card payment will be refunded in the original way. Usually the refund time is 3-7 days. After the refund, you can call the credit card issuer to inquire.

The second reason is that the credit card refund is recorded after the bill date, so this refund is recorded in the next bill, so it cannot be deducted from the current debt.
