djdj This looks too good to be true.
Those looks, that service list all for £100 ph?.... There is a private gallery which could be a/the scam.
The phone is on but no one is picking up. My qualification call would be hours worked, extras charged (Fk and CIM for me), pictures you and recent? If you cannot speak to her it will certainly be a pimp.
How close is her location to you? I will not travel for a TOFTT - too much time invested - but if you are passing you could arrange to pop in. Don't hand over the cash until you have the right answer on each of the following.
Sexy?
Smells good (her, room, bed)?
Services (and extras) as discussed?
Smiles?
Any fails and you should walk. Good luck and let us know if and how you proceed.
