JPMorgan Chase & Co. Credit Card Complaint

JPMorgan Chase & Co. Credit card department,

Other fee Maryland

I have an account with chase that has been at 29.99 % since they took over my account in 2007. Every Time I call they just tell me that 29.99 % is the best rate they have to offer. I do n't understand how that can be true if 29.99 % is their default rate. I been trying to work with them they say they will review my accounts in 6 months. six months passes and its the same thing, I get no results and just the run around from them. I need some one to do something about this.
