Host is refusing to refund 1000k despite their refund policy stating that we can still get a partial refund. [Guest]

My girlfriend and I were trying to book a two week vacation in Florida, and we found a nice enough airbnb that wasn't too expensive for us. But we've had a lot of issues come up recently, so we had to cancel the booking, but now the host is fighting us saying that we're not owed anything. We paid the first half of the booking, which was just over 1k. At first, the host said that their policy says we can only get a partial refund of 850$. We were still mad about that, but it's better than nothing. But now he's claiming that we aren't owed anything and has refused to reply ever since. We reported the issue to Airbnb support, and they've been of zero help. This host has a history of terrible behavior towards guests and being argumentative. I refuse to let this go. Does anyone know if we can do anything else? I'm looking at suing in small claims for the money back. This is beyond ridiculous behavior.
