The ‘host’ creates a fake listing, usually using another listings photos. If you view the site through which you booked, and check the URL you’ll see it’s not the authentic Airbnb site. If you’d booked through the actual Airbnb site this would not have happen and can’t happen, because of the way the payment system works.

So, it’s nothing at all to do with Airbnb. It’s just between you and the con artist whose con you fell for.
