Wilson Dental PC False Bills and charges from Dentist even after speaking to Billing Dept who acknowledged mistake Syracuse New York

4 months after my last appointment at Wilson Dental to get fillings for a tooth. I get a bill in the mail stating my balance overdue is $254. I have dental insurance and I always made sure to pay my dues before leaving the premises. I have statements that show balance overdue as 0. But the dentist sent me false bills and asked me to pay $254 immediately. 

I have a good credit standing and the last thing I want is these morons to sent a fake bill to collections. I call Wilson dental and ask for the billing department, they keep transferring me to the billing department but no one answers obviously. I leave messages and no one gets back.

After calling over 12 times, I speak to the billing manager Taniel.  She says that she has gone through my payment and insurance claim transactions and history and she is not sure why my balance is $254 and asks me to disregard the bill and says that my balance is 0. I asked her to send me a statement saying my balance is 0. 

Fast forward one month later, I get another bill from Wilson Dental PC stating that "This is the second Notice" Please pay $254 immediately. I have proof that everything is paid for, still these morons irresponsibly send me fake bills. It seems like someone in billing department is running a big scam and trying to send false bills to customers to pocket money. 

After having contacted this Wilson Dental 15 times - They still wont fix their fraudulent bills or send my a clarification for the wrong bill even after acknowledging their mistake. I have left another voice message today - 10/29/13 and I am sure Taniel wont get back to me until I keep pestering them. Makes me wonder what they are upto.
