I booked a flat yesterday and received a message from Airbnb Support today saying that my host can't provide this flat anymore due to 'reasons' and that I should expect it to be cancelled within the following 24 hours. The host doesn't reply to any of my messages, even those I sent to her phone number posted on the confirmation page. The booking, however, still remains accepted/not cancelled. I'm still within the 48 hour period of full refund. I also don't want to sit here waiting for 24 hours.
What is the best thing to do in this situation?
