Debt Collector repeatedly tried to collect a XX/XX/XXXX debt I allegedly owed my graduate school for medical services/prescriptions not covered by my school insurance plan. Over the phone, my mother paid the debt collector {$410.00} by credit card on XX/XX/XXXX, based upon their employee 's verbal promise to reimburse her if we could prove the debt had been paid by the insurance company. If I ( or my mother ) did n't pay that day, the employee said they would make an adverse report to the credit bureau. My mother sent them a statement from the insurance company reflecting they had paid the school but the collector will not refund her money despite her written request.
