Capital One Credit Card Complaint

Capital One Credit card department,

Cash advance California

Recently - less than 1 week ago ) I was short of funds and had to take a cash advance on my capital one credit card. I received the necessary funds to repay the full balance of the cash advance and called to get the I formation on how to do this. When speaking to the representative, I asked him what the procedure was to accomplish this as I have always been able to do this in the past with other credit cards. - '' the representative insisted that this was not possible and stated that the payments are always applied to the lowest interest rate - and then they would go to the highest interest rate charges after all of the other balances were paid -. This is totally unacceptable and potentially criminal! So what they are telling me is that I will be paying 30 % on the cash advance until I pay my entire balance in full?!? I told the rep that what he was saying was wrong and he proceded to tell me that they ( Capital One - WOULD not help me. I have already been charged - separate $10.00 cash advance fees, which I understood and acknowledged before I made the withdrawals, but what he is saying was rediculous! I told him that I was going to report them to a government agency, and he was very rude and still very unhelpful. I am certain that there are laws prohibiting credit card companies from doing this. Please advise me of my rights in regards to thisThank you.
