2 different hosts have cancelled my reservation with very short notice. Need some advice!

hello r/airbnb, any advice on this would be appreciated! Thanks in advance!

In March, a group of 6 friends and I made plans to go to a concert in the New England Area for the July 4th weekend. We all got days off from work for the Thursday and Friday before etc. Naturally, I booked an airbnb (in March) for the trip. I did this knowing from experience that there would be nothing left if I waited much longer closer to the event date. Put about 800 bucks on my credit card, and everything was fine until about a week ago. The host cancels on me saying that there was damage done to the house over the winter and its unsafe to occupy. Sure, this might be true, maybe there was some damage done over the winter and the house may be unsafe to occupy. But it struck me as convenient that they didn't know about this damage until June! So now within a month of this massive event we had no place to stay. After some back and forth with air bnb we managed to get another reservation, one of the only ones available but much father away from our original one. Air bnb covered the difference with a voucher, totalling 200 bucks. Just getting this 200 dollar voucher I had to fight tooth and nail. Whatever though, at least out of the woods again...until...just yesterday this new host cancels on us ALSO citing unrelated damages to the house that make it unsafe to occupy. So now once again, we don't have a place. There are no places within 20 miles of where we want to be anymore, except one which is 400 a night(way out of our original budget). And the concert is now less than 3 weeks away. I'm frankly sick and tired of airbnb's customer service at this point. The whole point of booking this in March was to get it out of the way EARLY. Is it reasonable to ask airbnb for money back on our original payment AND a voucher to cover this really expensive place? I am not putting any more money into this trip, and I'll be damned if we don't get some sort of goodwill refund from them. I've wasted hours trying to fix this situation and it's been extremely frustrating. The best case scenario would be to get this 3rd reservation without paying more than my original payment AND to get some money back. Is it possible?!?
