I cut my cards into little pieces 3 years ago. After 5 1/2 months in the hospital, the slimy companies had bucked all my interest to 31% annual. They refuse to do anything whatever to work it out, even reduce the interest in any amount. So I got payout numbers, paid them off, but STILL the asses called. In art least one case, I had overpaid and they owed me $. STILL they refused to reduce the interest rate, so I called them and cancelled all the cards EXCEPT Amex.
Amex had suspended charging, but accepted my explanation and reinstated my card. There were a couple of giltches, but calling them got is fixed on the spot. They apeared to "care" about the business relationship.
All the rest pretty much said they did not give a damn abiout me or the horse I rode in on, so why should I care about THEM? I don't, and my reccomendation is that you all put yourselves in a position where you can terminate them with a payoff and closing the account. Then, if they refuse to give you the interest of fee schedule you want, FIRE the bastards!
It won't take long before they are begging for your business, but EVERYONE needs to do this.
