My host has been unresponsive the entire day of the check in day. I raised an issue with Airbnb, and they couldn't reach out either. They are only able to offer refund/cancellation for my stay, which I booked more than 3 months in advance. Now I don't have accommodations, and all hotels are at least 3 times the cost, which Airbnb will not reimburse. I am not sure what to do. Can someone help?
