Capital One Credit Card Complaint

Capital One Credit card department,

Closing/Cancelling account Massachusetts

I applied a credit card from SAKS FIFTH AVENUE and I received the card on - -. I found it blocked and I made the phone call to unblock it on - -. I provided all the document required to verify my identification. Now it 's still under review and I can not get any estimated date. I can even not login my account online. I can also not cancel this card. It 's really stupid and the customer service just keeps saying they can not do anything while it 's under review.
