I was offered a credit card with an introductory rate of 0% a few years ago. I applied and recieved it. After the introductory period my interest rate was 7.99%. A few months ago I realized that my minimum payment was very large. I looked closer at the statement and my interest rate was 27.79% I was never late and never went over my credit limit. I pulled out past statements and found that my rate had been increasing just increased. I called Advanta and was told that they were re-evaluating their interest rates and there was nothing I could do. I could check back in 90 days to see if there was a better rate available. I asked to speak with a supervisor and was told that was not possible. They told me that I was sent an opt-out letter that I had never recieved. I paid off the balance this month by movin it all to a new bank for 3.99% until 2010. Looking on-line I see that this a common event with Advanta. Can't SOMETHING be done? It's cost me a fair bit in interest and has probably negatively affected my credit rating. Thank you
