XXXX XXXX XXXX repeatedly sent statements indicating a bill was unpaid. In fact, I had used my XXXX Visa card to pay and received an email receipt. I took several actions to relay to them the payment had been made. These actions included a phone call, where I was assured the problem was resolved. Upon receipt of another statement I sent them fax copies on XXXX dates of the payment receipt. 

Despite these actions they sent the issue to a debt collector. I have received XXXX letter from the debt collector and have responded in writing disputing the debt.
