I was just recently in a situation where a host rejected the rental price after booking, and convinced the support team that i agreed to the adjusted price, which was then charged against my card. (To be fair there was some messaging back-and-forth between myself and the host prior to the booking that gave credence to this, but nothing official.) When i rejected the new price the host agreed to cancel, then again convinced airbnb to execute a guest cancellation, forfeiting all but $613 of a now $4400 booking.
It took me roughly a week with those funds tied up before i found someone in their support team (O.G. Lou G, i love you man) to actually listen to me and reverse everything.
This on the heels of renting a condo with hammer drills running upstairs 8 hours a day for the last three days of my trip and zero consideration or recompense from the host or airbnb.
