Did Capital One send you this letter?

"Due to extraordinary changes in the economic environment, we're reviewing our existing credit card accounts. Having considered these economic conditions, your account's current Purchase rate, and the length of time you've had this rate and account, we will be changing your Purchase and Balance Transfer rate."
What does that mean? They are raising my rate by 10% and the guy over the phone said it could have been up to 25%! When I asked him what list of qualifications are to choose what accounts get this rate increase, he and his manager would not tell me. I also would like to state that I have never had a late payment and pay well over the minimum monthly payment. So what did I do to deserve this? Didnt they already get enough of my money with my old APR rate?
So if you have an account with them I urge you to decide not to accept these terms and close you account. I feel that this company is taking advantage of the recession and do not deserve any more of my money....or yours.
