Bank of America Credit Card Complaint

Bank of America Credit card department,

Delinquent account Florida

I opened my first credit card about 6 years ago with Bank of America. I ended up closing my account 2 years after initially opening the account. There was a $30.00 annual fee with this credit card. Those fees were paid in full with zero balance. Now, I am trying to refinance my house, and I have a $18.00 balance that is long past due. I was never even notified about this past due balance. This is affecting my credit, and I need this $18.00 balance removed immediately. I feel this balance is an error, but I am willing to pay the balance. I greatly appreciate any assistance.
