I ha d medical services  rendered  in  XX/XX/XXXX .  At the time I had insurance and the provider was in-network. The provider group was subsequently bought out by another company several months later. In  XX/XX/XXXX  I received a bill from the old group 's billing company  XXXX   XXXX   XXXX   XXXX   XXXX   XXXX  for the full amount of services that were rendered. I attempted to call the company several times and finally received a call back from a man there that stated that he was the only person in the office working these accounts. I asked him if it was sent to my insurance company, he said it was. He then stated that there was no response from the insurance so he placed it in patient responsibility. I explained to him that this was adjusted to my in-network deductible and that he needed to call my insurance and obtain an EOB and adjust my account so that I can pay. He then proceeded to be very rude stating he did n't have time to contact my insurance company and that it would be my responsibility. I tried calling the doctor 's office that was bought out but they said they could n't help due to the buy out. Because of that I mailed him a copy of my EOB mailed to me by my insurance. I did n't hear back about this unt il  XX/XX/XXXX  wh en I received a collection letter fro m Fidelity National Collections. I formally disputed the amount owed. I explained to them that I did  n't owe the full amount in question and faxed them a copy of the EOB that I had printed from the insurance company 's website. They said they would go back to the original creditor to see what they wanted to do. After many numerous follow up calls that I made to them ( they never contacted m e ), I fi nally received a response on  XX/XX/XXXX   . They gave a very ambiguous statement made by the original creditor of why I owed the full amount and said that I still owed the full amount even though I sent proof that I had an in-network deductible and they were balance billing me the full amount. No where  did Fidelity  or the   XXXX   XXXX   XXXX   XXXX   state or provide in writing to me that the provider was out-of-network. I then contacted several managers, who I ended up speaking to finally was  XXXX  I believe his name was on  XX/XX/XXXX   . He said that they have to stick with what their original creditor tells them. I told him that I do not owe the full amount in question and would pay that day but only what my in-network deductible was. He said that the original creditor probably would n't go for that. That day, I involved my company 's insurance broker,  XXXX , on the matter and she was very helpful. We spoke to  XXXX  together and he stated he would get the original statement and would get back to me the next day. That never happened so we called  Fidelity t ogether the next day. We spoke with a man who said that  XXXX  was out and that he had no direct line, no voicemail or email and said he would contact us in a week. After several weeks with no response  XXXX  suggested that I contact you for help resolving this claim. I am more than willing to pay what I legally owe. I have verified with the insurance company that that provider was in-network at the time services were rendered. They are trying to balance bill me for what I do not legally owe and   XXXX   XXXX   XXXX   XXXX   and  Fidelity National Collections a re both neglecting the legal contractual obligation of in-network services. I would appreciate any help in the matter.
