bank loans are automatically deducted when they are due. Generally, the system automatically deducts them after the end of business. The general time is between 19: and 2: in the evening. If your loan is due today and there is enough money in the agreed repayment account, it should be deducted after 19: . If you deposit money in the wrong repayment account, you won't be able to deduct the money. Then you need to go to the bank counter to repay the loan manually tomorrow.
