Capital One Credit Card Complaint

Capital One Credit card department,

Closing/Cancelling account Ohio

Capital One closed my credit card account without my permission. I recieved a call today saying someone called previously and requested my account to be closed. I do not understand why my account would be closed without my permission and without contacting me. The lady I talked to said she was calling to clarify why it was closed and kept saying I requested it to be close. I told her that was not the case and that I did not request the account to be closed but she would not listen to what I was telling her and just kept repeating that I had requested the account be closed which of course I did not. I could not seem to get her to understand this and she eventually hung up on me. I have never seen customer service like this. I do not appreciate Capital One taking liberties with my card and closing it without my permission.
