Citibank Credit Card Complaint

Citibank Credit card department,

Rewards New York

On - -, 2016 I received an email at - that my Citi - - credit card was compromised. The company stated that they would re-issue me a new - for my security. I was able to use the one I had in my possession until the new - came in. On - - I tried to use my credit card at - of the merchants I usually purchase from and the card was declined. I called customer service and was told that my account was completely closed as of - - and they could not give me any more information. I was told to wait until a letter arrived in the mail from them. I called back later that night and told them that I had $8200.00 accumulated in my cash back rewards that I had been saving throughout the year. I was told since they closed my account that I forfeited the amount I had been saving. I have never had a missed or late payment. I have been to a Citibank branch and have called numerous phone numbers and have not received any help in resolving this situation. All I hear is " wait for the letter '' and as of - - I have not received any letter explaining the closure of my account.
