If there are problems such as non-repayment in the repayment process, the cardholder can ask at the Agricultural Bank outlet with the repayment voucher and wait for the bank to give a solution. Or call the ABC Credit Card Customer Service Hotline at 400-66-95599 to explain your problem to the manual customer service. If repeated deductions are made due to the ABC system, ABC will take the initiative to adjust accounts for customers.
