I had a medical bill that was owed from XXXX 2009 for {$540.00} to XXXX HospitalXXXX @ XXXX XXXX XXXX, XXXX XXXX TX XXXX ph # XXXX acct # XXXX. The collection agency Commonwealth Financial systems Inc ph # XXXX sent me collection letter on this. I pulled my credit to see that they had the same amt XXXX on my report. I called XXXX Hospital/ XXXX XXXX Services and the bill was due which i moved and did not get the bill. I settled the acct on XXXX for {$160.00} and paid it and told the rep that the XXXX acct they had was a dup acct and they were supposed to contact client on matter which has not been done. I called the client to find that they do not know who Commonwealth Financial systems Inc is. The client said they work with XXXX XXXX XXXX ( collection agency XXXX XXXX XXXX XXXX XXXX XXXX XXXX, TX XXXX ph : XXXX and they also have the account and balance and they do not know who Commonwealth Financial systems Inc is. I called Commonwealth Financial systems Inc and spoke to the collection manager XXXX XXXX XXXX on XXXX and told her all of this and she stated that they will not call the client and that I needed to resolve this even if they have the wrong details and will not contact the client to resolve. Therefore I consider this FRAUD and they have been paid nd I have a letter from them showing it was settled for {$160.00}. I need your help in resolving this matter due to they are reporting on my credit.
