My last statement for ICICI credit card had outstanding bill amount as 9000. After the bill was generated, I got a credit of Rs. 12000 from a refund. And, some other purchases in the month, right now, I have an outstanding amount of 1500. Should I make the full payment of Rs. 9000 for the last bill, or since I got credit in the month, I shouldn’t make any payment?

I called ICICI customer care and they are telling me to make just the minimum due amount of Rs. 400 and I will not be chraged any interest on the remaining amount.

What should I do?
