I definitely understand his anger towards this company. I have been invested here for almost 8 years now. It is absolutely shameful how they have treated their long term investors.
I am a gambler, I put money in slots and it usually pays or loses pretty quickly...This has lost and not paid off..But maybe it will land on 777 and I can get my money back..A real LOOOOOOOOOONG shot!
