Generally, the automatic deduction of credit card of CCB is twice. CCB will deduct the agreed repayment account on the morning of the due repayment date, so it is best to deposit the due amount into the account before 7: 00 am. If the deduction fails, the bank will make a supplementary deduction on the morning of the third day after the due repayment date, and the successful supplementary deduction will still be regarded as normal repayment.

Cardholders should pay attention to the following points when repaying their credit cards through automatic repayment:

1. If the cardholder has used automatic repayment, do not repay on the due repayment date to avoid repeated repayment.

2. The account opening certificate number of the bound account should be consistent with the account opening certificate number of the credit card application.
