If there is a way can i have my coins back or at least ban and get my friend Aizen90 ACC back

So i have seen and got scammed by a guy called DDG_zeKeR, he scammed my friend Aizen90 ACC and ask me for money on my friend's ACC. He also bought a e2 from me and say he will pay back since one my friend say I can trust him, I totally got scammed 1.2m, I rly hope Mr.Robby can come and do something ...
