It is stipulated that I should handle it myself.

However, if it cannot be handled under special circumstances, you can contact the customer service hotline of CCB to apply for authorizing others to handle my credit card business, and you need to provide a power of attorney. Please consult CCB customer service for details.

For the cardholder himself, after the repayment amount on the credit card is paid off, you can call the customer service hotline to cancel the account.
