Capital One Credit Card Complaint

Capital One Credit card department,

Closing/Cancelling account Pennsylvania

I have a family member listed as a authorized on my account. I received a letter that Capital One to destroy the card because the authorized user was removed because of past criminal activity. They were arrested but never convicted. I called and was told the decision woul not be reversed. I am responsible for the account not the authorized user. Again arrested but not convicted. Thank You.
