Hello, judging from the screenshot, the application for installment has been successful, but the bill will not change until 2 days after the installment is successful. It is the same as when you usually use your card to make purchases, you can check it through online banking 2 days later. According to the principle, the installment amount can be repaid from the next month. What needs to be repaid in this period is: (bill amount - installment amount).
