Capital One Credit Card Complaint

Capital One Credit card department,

Ohio

I have a credit card account with Capital One. The limit on this account is $500.00. I took a couple of cash advances when the account was first open. I have made purchases also. Never have I exceed the $500.00 dollar limit. However on each monthly statement, " Balance subject to interest rate '' on purchases amount changes after each payment. It either goes up on down depending on purchases and payment. The interest on " Balance subject to interest rate '' is the same as Cash Advances. The balance on CASH ADVANCES has only decrease less than $2.00 over the last two years, BUT the interest rate is the same as for PURCHASE. Payments have been made over the last 2 years. No portions of my payments have been applied to CASH ADVANCES. There were times that I paid more than the minimum on this account and NOTHING has gone toward the CASH ADVANCES balance. HOWEVER, I am being continually charged the same interest rate and not seeing a declining balance. Each month this company is getting an extra couple of dollars buy not applying any of the payments toward cash advances. All payments goes to purchases until this account is paid off. But there is the interest charges continuing on cash advances even if you make more than the minimum payment amount.
