If the cardholder wants to cancel the CCB credit card, he can pay off the debt in the card first, then take out the overpaid part, and then call CCB customer service at 95533 and call 86-28-95533 overseas. After the connection, he will turn to the manual service to apply for cancellation. After the application, CCB will cancel the registration, and then officially cancel it 34 days later. Note: If the cardholder generates a new transaction within 34 days after registration, the cancellation will be invalid.
