But, this is likely a blatant lie from you, nobody scammed you, or you can show us your prove.
I don't want to defend OP, but I remember that at some point in the early days of my twitter account, a Vitalik Buterin asked me in PM if I'm interested to buy ETH at half price.
I remember that I had neither money, nor interest in ETH back then, hence I turned him down, although he was pretty much insisting. Then I've got more experienced on what's this and that and I understood that I was sooo lucky to not fall for a (now obvious) scam.
But again, OP may just simply trolling, who knows?
