Citibank Credit Card Complaint

Citibank Credit card department,

Closing/Cancelling account New Jersey

I have had a citi credit card for a long time, since 2007. In fact it was one of my highest limit cards ( about $14000.00 line of credit ) and one of the oldest accounts I had. I had not used the card for quite sometime and all of a sudden it was closed without any prior notice to me. I just received a message saying my card was closed. There was no balance on it but if I had known my card would be closed for non-usage, I would have used it! I believe Citi did this because they wanted to switch away from the old rewards system model for that particular credit card. I believe their action has adversely affected my credit score and I did not deserve this. I did not receive any notification prior to being emailed that my account was closed.
