Welcome, I would consult with a lawyer that specializes in lemon law for an idea if it's something you should proceed. Either way, since you are this deep and obviously not happy I would cut ties if you can't get out of it via legal action.
If you think you MIGHT have to go back and forth it's just not worth it honestly. It's a lot of work to tune/remove then redo it all again for a quick visit, just to do it all over again.. Your best bet is to figure out just how strict your area is.. I've heard it going both ways, some places...
