10 working days.
If the repayment has been successfully negotiated, the bank will also have a waiting period. Generally, the account can be written off in about 10 working days. They have a time to submit the application for approval.
If the negotiation is successful, the staff will ask you what day of each month it is more convenient to repay. Note that you cannot remember the time of each period, so you must think clearly on what day of each month you can repay. It is best to repay the money two to three days after the salary is paid. You can negotiate with the bank staff. Generally, if the negotiation is successful at the beginning of the month, the money will be repaid before the end of the month. If it is not the end of the month, it will be repaid the next month.
