Bank don't inform me the correct rules and regulations of agricultural Loan interest at proper time. I have paid 3% interest one month before the due date. But bank send me a notice which inform me that the interest raised from 3% to 7% only after three months from the due date. I faced difficulty to pay the excess amount now. So I want to return the excess amount which I have paid.
