I second what all the rest have said. She should have had a take in form for you that would discuss the specifics of what was to be done and if any variation on that, a phone call or visit by you to discuss it PRIOR to the variation being done. I would definitely find someone else. When you do, explain to them what has happened to you already and go over what you are expecting from them. I would also ask them to see if you could contact a couple of their customers to ask their opinions of her/his work. If they do a good job, there shouldn't be any problems with that.
