Why didn't the bank inform me to send a text message to China Mobile?

Actually, it's all because the bank wants to make money from you. After all, the cardholder's credit card is overdue and there is a penalty interest. Don't underestimate the penalty interest of credit cards. Although the amount in one or two days is really small, the penalty interest is calculated according to compound interest, so if the cardholder fails to pay off the money for a period of time, the penalty interest will become larger and larger, and finally even exceed the principal. Therefore, Bian Xiao suggested that in order to increase the amount of credit card transactions, you should know more about your credit card billing date and repayment date to avoid credit card risk control.
