Several ads with fake pictures! (gothenburg - Haga)

There seems to be something weird going with several of the following escorts.

ANABELL (27) -0765914931 - Fake Pics, A completely different girl opened the door. And after i left, i got a text saying; "come back in 1 hour and Anabell will be here"
NADINNE (27) -0760885879 - Staying in exactly the same apartment as Anabell and her friend.

TINA (29), VICTORIA (21),TATIANA (28),SAMY (21) <-- Not 100% sure. But probably fake as well.

Im not sure, But i think there are more ads like this. And i've seen it before. And i recognize the girl.
If you say no thanks and leave. you get a text saying that "sorry, real girl will be here soon"
And it all has this kind of strange feeling to it. Like they get one girl and hope people wont say no, so she does all the work. =/

They usually don't know the ad very well either. Simply ask them what country they are from.
Always same response, first silence... then "what did it say on the internet?" And when pressed they usually get it wrong.

I have noticed that most of their telephone numbers are fairly similar to each other. and USUALLY start with;
0760
0764
0765
0769
So i would recommend everyone to be extra cautious when calling these numbers.
