Thank for post of that creepy guy!
It was the same situation with me. he found me throw TESOL course and asked to work with his family for a year. Because his children and his wife don't speak English.
He is gonna provide the own flat for me and pay every month 5000 pounds. which is crazy and unbelievable!
Guys, be careful!! And also if you check his phone number it is the number of company.
I won't never send to him £900. Fuck off, Jin Chen Tao!
