Citibank cannot correct mistakes THEY make

I had a Citibank Visa card for years. I made the payments every month. Because I get paid bi-weekly, the payments were sometimes a little late, but paid every month regardless. In July 1999 I received my monthly statement and it showed a $700 bounced check payment. So they charged me the $700 plus a bounced check fee. The problem was, I had never made such a payment. My payments were all made in cash at a Citibank branch in my area. I called them immediately and went through hell with their operator trying to explain that this $700 payment was never made to my account and that they mush have mixed it up with someone else's account. I was finally handed over to a supervisor and she was also rude, saying I had made some late payments and insinuating that I was trying to get out of it fraudlently. However, she assured me the $700 charge would be taken off as well as the bounced check charge. This never happened. They kept charging me, and because this charge put me over my limit, they charged me over limit charges as well. I felt the only way to resolve it was to make the minimum payment and wait for someone from the bank to call me about the debt. Well, they did, and it was worse than when I called them. Various times I was assured that the charges would be taken off. They never were. I had estimated that I had paid off the total amount owed, so I stopped paying them. Now I know that was the wrong thing to do. They took me to court and my repsonse fell on deaf ears in the court system. I even had documentation about everything and still they won their case. After getting my wages garnsheed for 3 years, they said the debt was settled. NEVER DO BUSINESS WITH CITIBANK!!! They can't keep their accounts straight, and won't even try to settle with you.
