Vadadent Modern Dental Group reviews

I went to this office with the authorization through my medical and red white and blue card and told me that they could do the deep cleaning and the root canal and that they require a crown. Halfway through the procedures of the crown they tell me, after starting the procedure, I have to pay money out my pocket. I don't think that is appropriate for them to start the work and then tell me I have to pay out of my pocket. I really want something done!! I would love to be able to sue these people for doing my mouth in this way. What could I do to stop them from ever doing anybody else like this? The company name is Modern Dental Group and I have serious problems with the way they handled my dental work I wouldn't allow them to complete the work. Because of what they did, I will be seeking damages. My tooth is still broken, started the root canal, then made another appointment to come back, then they told me that I would have to pay out of pocket. They never submitted this to my insurance.
