Suing a doctor for making a mistake in plastic surgery

I had rhinoplasty surgery. Prior to the surgery, the Doctor had agreed to perform an open rhinoplasty to refine the tip of my nose and adjust the bridge of my nose.

After receiving the payment from me for the surgery, the Doctor then refused to carry out the full procedure that he had agreed on and that I had paid for.

I would have never paid for the surgery had I known that he was not going to carry out what had initially been agreed upon.

I have also been left with a large boney lump at one side of my face, between my cheek, nose and going up to below my tear duct. This was not there before surgery.

When I received my discharge papers from the hospital, the Doctor had written down my diagnosis as "large nose", with no accurate diagnosis/description of the actual surgery that was performed.

I now have to get another surgeon to fix the bone sticking out of my face. I would like to take legal action against the surgeon that did this to me. I am looking for some advice on this.
