OH MY GOSH!
I would be so upset! I don't think there is anything you can do about the bill, but I would definately tell her how upset you are, and ask her to explain this to you. Tell her you want to understand, why this problem has taken this many times to resolve. The office should have a business manager you can talk to. Just remember that you get alot further with honey than vinegar, and if you start the conversation angry, they will be less likely to negotiate with you. I would call in and ask for the office manager nicely, and then calmly explain what happened. Tell her that you want to be happy about the care you recieved, but you can't understand how you needed a filling, three root canals and a crown, and the problem is still not resolved. Tell her you are very frustrated and broke! See is they will negotiate a deal with you. They want you to be happy. An unhappy patient, causes alot of bad publicity!
