I have been Citi Bank customer for 17 years. Last month I got an email from them and informed me that they had closed my Master Card account because it had zero dollar balance and I had not used it for a while. I called them and in the phone they also mentioned that they might also close my checking account because I had not used it for a couple of years. This proved to me that Citi was not a reliable bank anymore. I transferred thousands of dollars that I had in my checking account to another bank. A couple of weeks later Citi charged me $12 maintenance fee because my checking account had $3 balance plus $35 because the over drafted me with $12 of maintenance fee. I called them and asked them to close my checking account. The said they cannot close my account and the would keep charging me for maintenance fees and over drafting fees in consequent months. This is completely rubbery and is not expected from a large bank with over 200 years of history.
