Billing service for one of my doctors applied a {$20.00} credit from XXXX/XXXX/XXXX to a {$35.00} co-payment from XXXX/XXXX/XXXX leaving a balance of {$15.00}. The billing service 's inadequate records did not reveal that the good doctor refunded me the {$20.00} four years ago, therefore leaving no credit for the XXXX/XXXX/XXXX visit for which I paid the full co-pay of {$35.00}. {$35.00} minus {$20.00} leaves {$15.00}. Over a span of over two months, I repeated provided proof of the doctor 's {$20.00} refund and proof of my full co-payment of {$35.00} to both the billing service and the collection agency, First Federal Credit Control ( " FFCC '' ). FFCC tacked on the erroneous {$15.00} balance to my XXXX/XXXX/XXXX service date balance of {$210.00} for a total debt collection of {$220.00}. I paid the doctor the {$210.00} and provided proof of that payment to FFCC. In spite of my best efforts to clear my account, FFCC filed a notice of debt collection with the XXXX credit reporting agencies for the erroneous {$15.00}. After I called FFCC about the posting of debt collection with the XXXX agencies, the " mistake '' was admitted and I received a XXXX/XXXX/XXXX letter stating FFCC requested deletion of the erroneous debt from my credit. Why was it sent in the first place, after repeated attempts to clear the account? This is fraudulent. I also filed a dispute with the reporting agencies.
