Haha, if you read my review she did the same to me! similar to yourself - very smooth comms, when I got to the street, there was 100% radio silence.
She later called to apologise that her last client refused to leave after his session and that she got the police involved. I'm not sure how a punter will pay for an hour then refuse to leave when his time was up, did he hold her hostage or offered to book out her time slots against her will.
It was journey from Bank to her location, so I made my way back really pissed that day.
