[Resolved]  HDFC Bank — wrong charge to hdfc credit card - offus emi + payment of minimum due attracts interest!

1. My credit card is showing a charge as per below:

What are these charges? I want it to be reversed..

2. I always used to pay the minimum balance due. It was never made clear that minimum balance due will attract interest. This is a very deceptive manner of charging interest. It should have been made clear that minimum due will only ensure that penal charges arent levied but interest is. The high-interest rate itself is a charge.

How can such deceptive practice be carried out? I want these charges reversed.
