PJP Health Agency is a rip-off!!! They won't pay my doctor bill. Melville, New York

I had insurance with PJP Health Agency. I have been trying since december of 2010 to file a claim for a doctor visit they never paid. This is an in- network office and I have been told repeatadly that I am covered for the visit. When I first sent the claim in there I was missing a diagnosis code and another code. The director of the clinic that I go to called PJP Health Agency and sent them a letter with all of the information that they requested. However I keep getting the run around. One person will say that they have all of the information and the next person will say no we have never recieved anything. I asked if I could speak with the same person when I call and I have been told no. Everytime I call I get a different person who has no idea what I am talking about. I have never in my life delt with such a horrible company with the worst customer service EVER!!!!! The claim is for over $200.00 and to be honest I just don't think they want to pay me any of the money. I desperatly need help!!!! All it would take is for one person to take just 10 minutes of their time to look over my account and FOLLOW THROUGH!!!! This insurance is a rip-off.
