Hi @Brandy97
Welcome to the community 😊
I am sorry to hear about your experience and frustration.
The host's lack of communication didn't update the listing, and the announcement is inaccurate.
The guest could contact Airbnb Support Help Center to cancel the reservation on the host's behalf, request a full refund, require Airbnb to find a new place within the budget, and leave the listing immediately.
You could leave an honest review to the public of the listing is faulty and the poor communication of the host. Communication plays a vital role in the success and failure of the host, and correcting the listing is essential to the announcement.
