โดนโกงเงินก้อนโต

I was been scammed almost 1,200,300 $ dollars within short period of time . the guy started chatting me on WhatsApp and facebook he started advertising the platform investment platforms he convince me to the extent I believe he is a good trade. After I'm completely comfortable I decide to invest with him started from 500$ up to 1,200,300$ then I realize he is a scammer because I stop replying to me. Told to please help me with money later on he blocked me. So dont Trust Anybody to invest
