I'm sorry to be the first one to tell you in this thread, but this is a matter for the civil court. And you have done nothing in 4 years. I don't see any reason why I would believe what you are saying.
Go to the court and fix it within 6 months to 1 year. You are the one losing money here.
Maybe you are right, they have fake order books, but how that helps your case? If your afirmation is not right, they can in the same way attack you and you may lose all your money and maybe way more.
As a matter of fact, there is a legal procedure against the OP for defamation. You could find the official docs at the following link:
