You can't. Cancellation of credit cards must go through manual customer service, and mobile banking does not provide self-service cancellation of credit cards. Users can directly call the customer service hotline of the issuing bank, and after transferring to manual customer service, they can directly apply for canceling their credit cards, so that users can directly cancel their credit cards without going to the counter. After the credit card is successfully cancelled, the user can no longer use the card.
