Hi Jenna,
I am so sorry to hear that this happened to you. I really hope you are doing ok and taking it easy after your ordeal. Do you mind if I ask where in London you were when this happened to you, and what time of day it was? Did he know you had security there or did he think you were alone?
This sounds like a guy who walked out on me the other day, but it was a different number. I kind of felt something was dodgy but I think he may have got spooked because when he called for my flat number my flat mate was being very noisy in the background. He made out like he didn't know what my rate was and hadn't brought enough money because he had got a cab from east dulwich.
He then wanted to ring his friend who has apparently made the booking to double check the rate and then wanted to come back with more money as apparently he would be in the area (paddington) for a few hours.
This may or may not be the same guy but the physical
Description is spot on, except he was wearing a big white reebok coat, with dark jeans and white trainers. This was last Thursday at 9pm. He came from AW and his number began 075306872**
