Citibank — Credit card overdue

Address:	110051
Website:	Citibank.com

This issue is few years old as I was a customer with Citibank, due to some personal reasons I had to quit job and go back to my hometown, and due to the reason I could not afford it as well I sent request to cancel the card, but was not done for which I got to knew after 4 years when I came back to capital and tried applying for the new card.

I have been trying to contact them and get issue resolved as to what happen, due to the fact issue is quite old I am unable to find any correspondence for same.
