Oh, if you already paid, and you think the wife should be reachable, I'd be leaving a message about when he's coming to finish the job you paid for...but don't harrass him. Annoying people is different from just checking in. You never know, could be they were in an accident or something, so calling once every other day shouldn't be harrassing, if they are okay, then it should motivate them to come back out or give a refund. Hard to say, though.
I fell out of communication for a couple of days when my cell broke, but I tried to email everyone or call from home if I excpected to be in touch with them. So, at this point, I'm inclined to give the benefit of the doubt. If you dont' hear back in a week, and there's nothing in the newspaper..then I'd start calling and asking about the money at least.
