@Debra776. Hi Debra, this sounds awful. I am a host, like @Helen3 and others here on this forum, not Airbnb support: we try to help where we can so please be respectful.
So these guests are contacting you but havent turned up (yet)? Can you locate the listing on Airbnb, if so, report it again and the host. Yes, Airbnb should help more in getting the listing removed but it sounds like you also need help on the ground. While its being sorted I'd invest in a camera or two.
