Trouble using your card: Credit card

Last Sunday I attempted to make a subscription purchase online using the virtual card. My card company is Capital One. As soon as I tried, they denied the charge and immediately restricted my account. They requested documentation from me for ID and residency. Within minutes I uploaded this information to them. As of today, they haven't done anything with that information. Telling me I must wait several days. They claim they have so many cases to deal with and just can't get to it fast enough. It is widely known that Capital One 's automatic system doesn't allow for many day period before the system will automatically close the account. I have attempted to be proactive and have called daily to get updates. So far nothing has been accomplished on this. The representatives have been very agressive and some even just blowing off the situation as not important, you just have to wait they say. To them there is no sense of urgency or customer service. Please help!
