Did you buy private placement before it went public or did you purchase after it went public? If you bought before it went public, didn't you read any of your paperwork that said it was not a guaranteed return on investment? All stock investing is a risk at some degree. Private placement can be extremely risky because there is no guarantee you will even get your investment back. If it was guaranteed, everyone who ever invested in private placement would be wealthy. Buyer beware! Just because the sells pitch sounded good, does not mean you aren't responsible for being diligent yourself. Truth be told, you should never invest more than you can afford to lose. The odd thing here for you is whatever price you bought this stock at it is worth more than that now. So, why so angry? Why not sit back and wait until you can sell and make either initial back (which is no loss) or perhaps make a little profit. Profit is profit, no matter how big or small.
By the by, Apple, Google, Sony, Facebook, etc. get sued everyday. It is part of the game.
