Capital One Credit Card Complaint

Capital One Credit card department,

Credit determination Utah

I have had a Capital One credit card for years. The rate on my card was at 12 %, about the time the credit melt down happen Capital One increased my interest rate to 17 %. I was - day late in making my payment, but feel the rate increase was excessive. My balance on my card is about $18000.00 so this rate of 17 % makes it very hard for me to pay down. I have always made more than the minimum payments required but still do not see any relief. Please advise.
