i am surprised you giving this advice, had you down as someone with a bit of life experience, there is no possibility of him getting his money back with this approach, he has 2 choices, go to the police, or get even,that doesnt mean violence, this girl will have ripped off and scammed others over the years, and will continue forever, its part of their dna.
I dont know how the op previously responded, and as for scamming punters, I only see two scams, one being the op, and the other one being jakesnake884, if there are others please let us know
I see no reason in being polite, and asking escort, simple things, try and gauge if you get refunded
But also agree about the police part, so once you had your say, its now with the police
As for being scammed my self, yes I have, but well before we had, and the girl worked in a sauna, and borrow £50, which i found many years later was for her hash. I was polite with her, and new when I was at the sauna, but I was seeing another girl, she had money. I knew I wouldn't get my £50 back in one go, so she agreed to give me £20, and the rest later, which she did
