If you really don't want to use it, wait until you receive the card, and then see if you want to contact customer service for cancellation.
First of all, whether you want to cancel your credit card because you no longer use it, or you want to sell your account within the validity period because you don't want to use it, you should pay off all the debts you should pay, and the customer service should confirm that it meets the requirements of annual fee exemption, so as to ensure that you don't owe any annual fee, and then ask the customer service to cancel your account by canceling the card.
Secondly, the cancellation of most bank credit cards does not take effect immediately, and it takes some time to officially cancel the account after applying. Therefore, after the account cancellation is submitted, don't use cards and value-added services. In addition, the formal cancellation procedures should be based on the customer service instructions of banks.
The bank's terms are very strict. The application for account cancellation can be written, customer service or other ways recognized by the bank.
