I don't know what happens why you agree with him to send funds as your investment, besides, that is a random person from the internet and you dont know him better. I also experienced this last month, someone PMed me in my facebook account convincing me to invest in the mining company and I think that is relatively in that case. But I didn't trust anyone on the internet especially in social media, that easy to make a fake account.
Sorry for your lost, this may serve a lesson for you. Don't trust any investment form, the majority of them are Ponzi scam. Anyway, thank you for the warned you brought it here.
Ohh, I found out we are on the same group of this account and he made another account with the same name.
Probably, He has created a new account here.
