Credit card cancellation does not require a voucher format

After the credit card has been paid off, the cancellation method is as follows:

First call the bank's credit card center and ask about cancellation related matters. It mainly depends on yourself. Whether the card is suitable for cancellation, whether there is any balance, arrears, etc. If cancellation is possible, the bank will accept the user's cancellation application and deduct the annual fees payable for all cards under his account. After approval, the card cancellation can be completed.
