Sorry to hear you had a shit time OP.
I posted on the Hottie thread - I booked with her direct via her aw number with no pimp involved i don't think as I spoke to her on the phone so I reckon that WeChat number is a scam.
I hope that's all it is I had no issues. I'll probably try and see her again soon and will report back. Hopefully she's not working for any pimps like this already.

edit: I've requested the mods remove the netbirds link from my review that has this shitty wechat link.
