@Maria13899 I'm very sorry you had this terrible experience with the cancellation last minute, and Airbnb's bumbling CS. It looks like Airbnb did arrange compensation and new accomodation though, yes? You can't expect more than that.
It's the nature of Airbnb's that sometimes things go wrong, and a stay may need to be cancelled. It's not like a hotel, where if a room experiences some disaster and is uninhabitable last minute, they can just book you to another room. Airbnb hosts rarely have another house sitting empty next door that they can move you into. We wish.
If an unfortunate experience such as this is going to impact your health to such a degree that you consider taking your life, my suggestion going forward would be to stick with hotels, and purchase the maximum travel insurance that will cover all possible adverse circumstances you might encounter.
By the way, this is a community forum for hosts and guests to discuss issues and get help. It's not Aibnb CS or management you are addressing here. Just fyi. Best of luck to you, hope you get back on track.
