If you have a serious problem, Airbnb is nowhere to be found

New host. Had several reservations booked. Became concerned when I didn’t hear back from my correspondence with guests. Had one guest who became pushy and passive aggressive before her rental dates. Informed Airbnb. Customer service was good at mediating and said they’d protect me. To call them if I had a problem with guest. Guest was not a good communicator and had no graciousness at all. Wanted me to let someone into the unit before her, that had not made the reservation. I wasn’t comfortable with it. Airbnb had every excuse for the guest and said I should let other members of the group in that didn’t make the reservation. Ended up cancelling reservation. Reached out via text message to next guests cell phone, only to find out she never received my emails through their site. Tried to talk to Airbnb and some dope named Lyle senior case manager decided it was all my fault and I’d pay a penalty for it. Tried to call with new information that guests don’t receive email, got tossed around. Got contacted via email from Lyle even though I asked to go above him. Was told their community relations dept would call me back. They never did. Called them a day later. They disconnected me. Called again. They had no record of the day before a conversation and reiterated that the decision by Kyle was final. They never let me talk to anyone higher. I dumped their service, app, my reservations… Everything. They couldn’t care less.
