I am sorry to say this, but I think you entered into another shithole that is even worse than GM. Good luck you could have your money back before they flee.
Maybe I am old and outdated, but I would doubt most "business" schemes that promise to return 3% or more per day. Such model has an infamous name. Hope this says enough.
