I received a letter from Credence Resource Management saying their client, XXXX XXXX XXXX, had purchased my account. This was for a medical bill from an accident that happened in XXXX 2014. I had quite a few bills from this accident that I had to work to get re-submitted and paid by insurance and I believed I had dealt with all of them. This bill was for {$990.00}. After calling, they told me they could not re-submit my bill to insurance as too much time had elapsed. When I pressed that this was not my responsibility and there must be a mistake, I was put on hold for XXXX minutes. When I talked to the representative again, she indicated there had been a mistake and that I only owed {$70.00}. I asked why I owed this amount and after a lengthy explanation ( none of which made any sense ) I told her I was concerned this was a scam. She asked me if I wanted to speak with a supervisor and put me on hold. Very quickly someone else got on the phone and informed me that I did n't owe any money and apologized for the inconvenience. I do n't know how these people got my medical information, but it seems like a clear scam where they were trying to get me to send them {$990.00} by claiming my insurance did n't cover a medical bill and trying to hold me responsible. This company SHOULD NOT be allowed to keep doing this to unsuspecting US citizens ( I did a search of Credence Resource Management and all of their employees on XXXX are based out of XXXX, XXXX ). This company is either blatantly scamming people or hacking and stealing personal information about medical bills and then sending fake bills. This is not right and I hope someone can stop this from happening to other people.
