How do I ask my orthodontist for a refund? He's messed me up terribly, along with his chosen surgeon

I started with my orthodontist b/4 a double jaw surgery that ended up Botched. My ortho started expanding my teeth extensively before the surgery -- the DJS expanded me more & pushed me over the edge. I'm still in braces with this same ortho & have been interviewing Revision surgeons for the past 2.5 years in a standstill. I have current models of my teeth and my teeth are coming out of the bone. A new orthodontist has to get my teeth back in the bone before a revision surgery.
