The credit card debit time of CCB is automatically debited from the agreed repayment account on the morning of the due repayment date, and the cardholder must deposit the repayment amount in full into the agreed repayment account before 7 am. If the funds in the agreed account are insufficient, the deduction will be made in the form of "as far as possible". If the deduction on the same day is unsuccessful due to the time difference handled by the system, the deduction will be made on the morning of the third day after the due repayment date, and the successful deduction will still be regarded as normal repayment.
