If the card is invalid due to overdue, you need to pay off the arrears first, and then call the bank credit card customer service to apply for restoring the credit card.

If the failure is because the bank suspects cashing out, you need to provide proof that it is not cashing out, otherwise it will be difficult to recover. If the card is damaged and invalid, you need to call the bank's credit card customer service to apply for card replacement, or go to the outlet to apply for card replacement.
