The due repayment date is also called the final repayment date. If you don't repay in full before the due repayment date and you don't choose the minimum repayment amount by credit card, then you may face the following penalties:
1. All consumption funds no longer enjoy the interest-free repayment treatment, and the bank will calculate the interest on a daily basis with the consumption amount as the principal, with a daily interest rate of extremely high.
2. I received a call and a letter from the bank.
3. Freeze your account and feed back your arrears record to the People's Bank of China and record it in your credit file, which will affect your personal credit.
if you really don't have enough money to repay in full on the due repayment date, please choose the minimum repayment amount by credit card, and only 1% of the total expenses will be repaid in this way, so that although there is no interest-free repayment period, personal credit will be avoided.
