BuyOwner.com franchise is no longer able to serve us. Am I entitled to a refund?

I don't know if this is the right catagory but my wife and I listed our house with Buy Owner .com about 3 years ago in Arizona and we recieved a leter twice from them saying they will no longer be able to serve us a agreed on in the original agreement. We paid them $2,850 up front to list the house on there website and if sold would do all the escrow and all paperwork for that price. In there letter they wanted us to sign the letter and release them from any obligations with no refunds coming back. The one thing they said they would do is keep it on there website only. Tried calling them and they said the franchise in Arizona was lost and confirmed there would be no refund. They said they had nothing to do with the franchise in Arizona . Are we entitled to a refund?
