I cancelled the card last week after an angry conversation with a "customer service" supervisor. Their sorry customer service lost them over $40,000 in annual charges as a card holder for four years.

I've had a few months where there was a significant disputed charge and I was charged finance charges. They were reversed two consecutive months after I called and pestered them to reverse what should have never been charged in the first place.

Last month, they only agreed to split the finance charge. It was only $8 that I paid, but it really ticked me off.

This month, I was charged $39 for an overage fee. I got married and had a $20,000 hotel bill. My limit was $10,000. The hotel charged the max that Chase would allow: $12,500, and then the hotel put the difference on another card. I hate paying finance charges or overage fees, so I called to request a reversal of the $39 as a courtesy, since they didn't take my whole charge and I always pay it off monthly. First guy refused, and the second guy, the supervisor, was VERY rude about denying it. So I told him "congratulations, you just lost yourself a good customer because of your sorry behavior." I sure hope somebody listens to that recording- a perfect example of what NOT to do.
