[Resolved]  Citibank — unfair charging on unactivated credit cards

In 2012, one of the citibank customer service executive offered me a credit card which was told to be free for life.When I recieved the card, I was informed that I there is an annual fees for card by the customer support team. I immediately declined to activate the card and asked them to close the card. Now, suddenly in the month of March 2013 after more than 1 year , I recieve an statement from citibank saying that I HAVE OUTSTANDING OF 350 DHS IN MY CARD which was due to the annual fees of the card.

I am baffled and emailed them regarding the same. I am yet to recieve any reply from them in this regard.
Kindly advice.
