in case of CMB credit card, if you need to modify the billing statement, because Baidu is a third-party public network platform, we can't directly verify your actual personal data. Please call the customer service hotline-enter the account opening certificate number #-check the password and enter the manual. Warm reminder: once it is successfully revised for you, it cannot be revised again within half a year. The bill issued in this period still needs to be repaid according to the repayment date shown on the bill, and the revision will take effect from the next period. Business credit card holders cannot modify the billing cycle.
