Citibank N.A. Citi Unethical business practices, Modern day thievery St. Louis Nationwide

This is for Macys card that I rarely use. My wife had used the card mid 2016. Very minor purchase under $100. I had paid off the balance completely in a couple months. Citibank has this scam where they try and say that there's at least $2 in a balance. It magically appears. Why would I leave a $2 balance? 

I was told by the customer service person that I had a $0 balance. Then I start receiving letters about me owing them. I called to find out and they told me that there was a $2 balance that carried over and grew to about $40 in about six months! I was more than shocked by this. As soon as they told me this I told them to cancel this account right there on the spot. The rep told me that Citibank had placed a negative mark on my credit because of Their shady, unethical, thieving business practices. They wanted me to pay off the balance. 

I received a letter from a G. Goldberg Vice President of Citibank N.A.stating that the above referenced account is now $0. It's interesting that I received this letter from a supposed VP when I told the customer service person that I am reporting this incident on the web so that others will be informed of their shady, unethical business practices. 

I would strongly suggest that you never do business with Citi, Citibank, Citibank N.A. If this company can steal a few dollars from you and times that by hundreds of thousands of hard working people, its a way for them to make a quick buck at the expense of their so called customers. It's beyond pathetic how this company operates.
