Need help with getting car painted

[55Nick15]

So I took my car to a guy 3 hours away to have my car painted in january. Paid $900. It's now may 12 and I've been talking to the painter throughout the process. He tells me two weeks ago it's done and I can come pick it up (tomorrow may 13th). I text him today letting him know I'm coming and he says he is with his son who does motocross and won't be in town. I ask him when he will be, says he doesn't know yet. This is the second time he's put off delivery. Is there anything I can do to get the car if he isn't home? Some sort of law about following through? I have a receipt but no date was established for when it should be done. I believe I said April would be fine.
