Over-limit repayment times means that the number of credit card repayments in the current month exceeds the specified repayment times. Different banks have different restrictions on the repayment times of credit cards in a month, but general banks stipulate that the same credit card cannot be repaid more than three times in a month, in order to control risks. If the number of credit card repayments exceeds the limit in the current month, the cardholder needs to call the customer service phone of the credit card to apply for lifting the repayment limit, and then repay the credit card by other means.
