If you want anyone to do anything about it, post some info of who the scammer is? Like the profile, etc. Just like Vod said, how do you expect anyone to help you when your description is so vague and nobody knows any details?

If you're posting any dox's, you have to move the topic to investigations first.

Anyways mate, never send first to anyone, especially if it's to the tune of $2k. That's a hefty sum of money that I'm sure nobody would like to lose. Use forum escrow and you would have been much better off than right now. Don't send anything to him now or meet his demands either.
