I had the same negative experience With No getting my money back, when I canceled after an hour of reservation.
I talked to costumer service person and clear said cancel my reservations and make sure the place shows available for new guest.
Well, costumer service is the worst, after 2 weeks of communication, ended up with : sorry but you didn't cancelled .. and the rest was just bubbling to not give my money back.
They blame the host saying he never answer back and host is the only one who can give the money back.
Never again with Airbnb.
It's or was the most disgusting experience in my life, while those fricking costumer agents are not even USA.
Hate myself of having the horrendous experience.
I don't think I can file a case in court .. would be a waste of energy.
