It is Fake Letter!
Nowadays, there is a lot of trick to cheat your money!
(I can say someone is selling your information)
How i know it is fake?
I went to find the this branch of office,
This office is closed and moved to other place.
I try to call the office number, there is nobody pick up.
After call the guy,
He tried to scare you but we scare him back.
Try to ask what is the office number and some details...
He is quite another side for a while,
He replies to call us back later...
I guess he will never call back anymore!
