There are credit cards, ID cards, etc. Ready for you to ask for the card number. Call the customer service number of the bank to which the credit card belongs. According to the prompt, choose manual (if there is a credit card exclusive management, you can choose directly), and make sure to cancel the account with a credit card.
Wait, tell customer service that you want to cancel your bank card. Of course, she will tell you not to cancel. Just tell her I don't want to use this card now. Be firm.
Customer service will check whether your credit card is in arrears, annual fee or interest. When you cancel, the customer service will ask you what to do with the remaining balance. You can choose two ways: 1, don't; 2. Call another card. After the customer service verifies the information, she will tell you that the cancellation is successful, as long as the card is destroyed by itself. Within 45 days, the account will be automatically closed without any deposit or withdrawal.
