If the payment is not repaid by the due date, the interest will be calculated on the total amount owed starting from the day of the first purchase of the current bill, at a rate of 0.5% per day. Keep counting until the day you reach your lowest level. The interest on the remaining balance will be calculated starting from the day when the minimum payment is made, which is also 50,000 per day. It will be calculated until the next bill. As for the consumption on the 18th, you need to check whether it was credited before the 19th. If so, it will be paid in this bill; if it was credited after the 19th, it will be paid in the next bill. You can check the bill for details. In addition, it is not a big problem if there are one or two overdue records. You cannot delete them. You just need to pay back the money quickly.
