Last year in the month of October 2011 i visited the doctor for minor earache and before seeing him i spoke with him how much he will charge me since i don't have any insurance ? He said he will charge me $ 60 since i don't have insurance and there won't be any other charges. He just prescribed me ear drops i made the payment at the reception and took the receipt stating that there won't be any balance left since i made the full payment. Now surprisingly after 8 months he send me a bill of $ 268 with credit of $ 60 and it seems now he is overcharging me saying that "LEVEL 3 SERVICE WAS PROVIDED" and i should pay this due amount immediately while the receipt which i have says "BALANCE DUE = 0", "INSURANCE BALANCE = 0", "PATIENT BALANCE=0" everything was paid and i left the office with this receipt. Luckily i am still holding this receipt and now he send me this surprise bill........i want experts to advise me wht should i do in this case ?
