Capital One Credit Card Complaint

Capital One Credit card department,

Transaction issue Washington

I filed a complaint about not being allowed to stay in my hotel room - night while in -, -. I was clear that I was allowed to stay the other nights, but the final night I had to get another hotel because the security guard would not allow me to enter. I have repeatedly provided information about this to Capital One. They came back and said that I did check in to the hotel. I did, but was not allowed to stay - of the nights. -, the partial refund request - the hotel refused -. Once again, Capital One is asking for this same information. Their own contract says I am protected against services not being provided, but instead of doing that they are deliberately making me provide the same information repeatedly and trying to wear me down. I am tired of this. I just want the partial credit. They keep deliberately messing this up and confounding the information. Even when I told them to cancel the account because I am sick of this - they refused!!! How can they refused to close my account? It just baffles me that they act this way. Where are my protections?
