Hey all,
I just read a couple pages then skimmed through the rest but I had to add to this.
In addition to raising your interest rates due to "the cost of doing business" credit card companies can and do run your credit history now and then.
About 4 years ago we had several cards with balances. The totals were way more than we should have had, but we were managing the payments fine and always paying a little extra. Well, one of the cards (started with Bank of America and the Citibank was next) ran our credit history and decided our debt to credit ratio was too high (even though we were making all our payments on time) so what did they do? Raised our interest rate! The Bank of America card was high already, 17%, but it was the Alaska Airlines card that we had a small balance on and we earned so many miles it was worth it. However, when the raised the interest rate it went to 28%!!!! We stuck with that one but then citibank did the same thing, raising the rate to 29%. It tripled our payment. So, while we were scrambling to try and get the rate reduced and come up with the payment, we ended up being late on the payment. They charged us almost $50 in fees and raised our interested rate again - to 32%!!!! It was at that point that we gave up. They wouldn't help us, said it was out of their hands, blah, blah, blah. We quit paying, went to a debt settlement company and have just one more to pay off. Citibank was by far the nastiest though. They made endless threatening calls and finally filed suit against us (for $11K - yeah, I'm sure the legal fees were higher than that!).
I will NEVER have another credit card. They are all evil and people that work for them and the credit collection companies should be ashamed of themselves for gouging and attacking fellow citizens just like them.
