I'm not going to pay a fraudulent doctor
Why would you want to withhold payment?
Why would I pay him when he didn't do good work?
I'm sorry you were given bad service. If your doctor treated you fraudulently, you should pursue action through your insurance or the licensing board, hopefully they will help you and keep the doctor from practicing fraudulently anymore.
Yeah right! All these people make up excuses to not pay for something and then regret it later.
I would not recommend you don't pay in case it comes back to haunt you somehow. You should definitely seek legal action against the doctor if you are sure you have a case for fraud.
