HDFC Bank — late fee, service charges, finance charges, overdue limit

Address:

Hyderabad, Andhra Pradesh

I am a HDFC credit card holder with credit limit 20000. I should pay 13, 075 on feb 6th 2015 but was not paid as I got married on feb 7th. I used arround 19700 credit limit which was due to pay on march 7th but they added late fee, finance charges, overdue limit which costs me extra 2700 to pay on that card. I dont want to pay for what I have not used. HDFC cards going on adding late fee and service charges even though I am not using the card. I am using this card since 6+ years it never happenned before for me. please resolve this issue. I would be much thankful to you.
