isn't this fraud? Do I have recourse?

[Katey Janson]

I am in the process of buying a flipped home. They made over 250,000 on the flip. There was a sign on the wall in the kitchen saying that a Jenn-air fridge would be coming the next week when we made the deal. We even asked him if it was counter depth and he said yes. Now, today (a month later) eight days before closing, he says he is putting in a Samsung or he can give us 1700.00. I have a picture of the sign that clearly said it would be a Jenn air fridge (to match the appliances). A Jenn air costs at least 3000 without a warranty. Can he get away with that? Isn’t that fraud?
