If the credit card has confirmed the delivery and completed the interview, it can't be returned. At this time, you can consult the issuing bank to see if there are any other solutions. For example, you can apply to increase the temporary credit limit, apply for installment payment, or adjust the repayment date of the bill, and so on. However, I suggest that you should be cautious when choosing to use credit cards to ensure timely repayment and avoid unnecessary troubles.
