mine went from 7.9 to 12.9 and never was late or missed a payment. i called my credit card company and they said it was due to the economy and i did nothing wrong. now i'm looking for another card.....check your account rate. it went up i'm sure.
mine was about to do the same thing and i got the notice the day before. so i paid the balance with check over the phone. the $15 it costs to do that is cheaper than the interest i would have been charged just this month...
