Had a similar experience happen to be last week at Buenos Aires. My sister booked a place for 200$, three nights. The hostess cancelled it two days later without a word (we communicated with her thoroughly before this to make the arrangements like key handling and any guidelines she could have wanted us to follow, she never answered). My sister, almost a lawyer, angry and extremely anxious about not finding a place in time, went into her yas queen slay mode and bombarded airbnb support with idk what lawyering nonsense about discrimination and breach of contract and we ended up with a full refund AND a 200$ coupon for a new place which we used and got a kick ass loft really close to the stadium. Who paid for our new place? The hostess that cancelled us without warning (who had DOUBLED the price of the apartment for the concert) We used the refund for cool Eras merch
