Ha! I have hundreds of these from various numbers! It's just a scam. Ignore or if you can be arsed, bored at work etc, play along.
The other scam, is that before giving you the door number, they suddenly ask for a deposit to a hijacked bank account. The house is usually some poor innocent sod/biddy, so don't go kicking it down!
If it's real, tell them to come to the window or at least answer a videocall. This usually shakes out the scammers.
I insist on a selfie-type photo or videocall before any booking. They can give their various bullshit excuses but no pic/vid = no booking.
This is Vivastreet where 90% of ads are fake/manipulated or as I've noted recently, they verify with one real pic, but then populate the rest of the gallery with a very similar model's pics via image search that is similar enough to make you think its really the girl (just not as tarted up/fatter/ bad day) when you turn up.
Always use a punting line.
We need to normalise, no video confirmation = no booking!
