China Bank's credit card account cancellation method: the cardholder should call the 24-hour customer service hotline to apply for account cancellation, and China Bank will check the status of the credit card under the customer's name. If the account cancellation cannot be completed immediately, the bank will cancel the account for the customer 45 days after the cardholder applies for account cancellation and there is no debt or balance in the customer's account; If there is still debt, the bank will take the initiative to inform the customer to repay as soon as possible and complete the account cancellation; If there is any balance, you can go to the branch of China Bank to return the balance.
When the credit card of China Bank is cancelled, all the subsidiary cards under its name will be cancelled. Supplementary cardholders cannot apply for account cancellation, only the main cardholder can apply for account cancellation.
If you have other specific questions, I suggest you call the customer service staff of the bank, hoping to help you.
