If the deduction on the same day is unsuccessful due to the time difference handled by the system and other reasons, the bank will make a supplementary deduction on the morning of the third day after the due repayment date, and the successful supplementary deduction will still be regarded as normal repayment.
note:
The repayment time of customers with other repayment methods remains unchanged. If the repayment on the same day is unsuccessful due to the transfer time difference and other reasons, if the repayment amount can be guaranteed to arrive before 7:00 am on the third day after the due repayment date, it will still be regarded as normal repayment.
