This company is not "professional" by any means! I was called and treated like I owed them money personally! They told me a $23 bill was now $52 and that if I did not pay the full amount they would keep it on my credit report! BE CAREFUL...THIS COMPANY WILL TRY TO STEAL YOUR HARD EARNED $! NEVER PAY THEM DIRECTLY....ALWAYS ASK FOR THE BILL WITHOUT THE INTEREST AND PAY THE DOCTOR DIRECTLY!
