Expenditure repayment of ICBC means that the cardholder withdraws funds from the bank account through the counter, telephone or mobile phone, and uses the funds to repay the consumption amount generated when using the credit card. When users pay and repay in mobile banking, they need to log in to ICBC App and select the corresponding credit card to operate. After payment is completed by other means, please pay attention to verify whether the corresponding amount has been deducted successfully, so as to avoid unnecessary losses such as overdue penalty interest.
