Hair on linens, heater not working; no reasonable remedy

I booked a yurt for my husband while I was hiking the AT. The manager was very polite until I complained later. When my husband arrived, he could not locate the yurt, because the name had been changed, and I was not told. The bed was made up with (animal) haired imbedded into the comforter and hair on the linens, which the manager was witness to and changed himself. The heater did not work. My intention was for my husband to enjoy the resort and its amenities, but he wouldn't go to the tavern after tge other experiences. Per our conversation, the manager agreed to a monetary refund that we never saw. After a month, I left a message asking for a call and I received a text saying that he would give us a $35 gift card to the tavern (which we can never use). I asked for a phone call and was told that he didn't have to call me, because this was his final offer.
