@Alisha79 If you arrive at an Airbnb and find that the property is seriously not as advertised (which I guess is what you mean when you say you were tricked), you have to call Airbnb right away to be rehoused and refunded.
I don't understand how the host held you "hostage," but if you were kidnapped or forcibly detained, that would be a matter for the police to investigate rather than Airbnb. The accusations you've aired here are alarmingly specific, and as others have mentioned it is baffling that of all the things you claim to have experienced you could only come up with three words for your review.
