Hey Nicole, I'm sorry that you fell into such a mess. I am a decorative, interior painter and a courtesy I provide my clients (as well as for my own knowledge), is a poster board, reflecting what I believe they're looking for. That, of course, doesn't do you any good now, but remember that & DEMAND that the next time you look for someone.
Without knowing what you're looking to achieve, I can't really instruct you on what you should do from here. I guess my best suggestion would be to first, figure out what you're looking to do and read your contract with your painter. If you're not bound by any restrictions, AND if the completed finish isn't what you & the contractor agreed upon, I'd request either a partial refund or a redo.
