[Resolved]  HDFC Bank — Unnecessary Credit Card Charges

I pay my credit card bills regularly way before the due date, however this time I was busy in some engagements and couldnt pay the amount in time.
I had an outstanding credit of 1, 271.49 rupees to be paid by 2nd Dec.
I was charged a late of 400 rupees on this amount on 5th Dec which is highly unjustifiable. I have paid the complete outstanding amount to avoid any further charges by the bank.

Also there are some other charges that are levied in my account, which I believe shouldn't be.
12/12/2016 SERVICE TAX 108.43
12/12/2016 CESS TAX 3.87
12/12/2016 Billed Finance Charges – Retail 374.57
12/12/2016 KK CESS 3.87

Please provide information about these charges and also revert the fees that have been levied.
