Capital One Credit Card Complaint

Capital One Credit card department,

Delinquent account Massachusetts

I received a letter from Capital One that my account is $100.00 delinquent. My account was charged off and given to a collection agency. The account was ultimately paid in full last week with confirmation of all payments. I have attempted to contact Capital One after receiving this letter but transferred to a voicemail. I have placed about 10 calls during the day to this number and all have been transferred to the same individual. I am attaching a copy of the letter received along with my response. The account has been paid in full, I have all documents from the collection agency, and I have all records showing history of payments.
