It's unfortunate that you are unable to dissect and scrutinize the documents for yourself, or with the help of someone qualified. Relying on a posters opinion for your DD appears to be your downfall. The company was not sold as a going concern. It's clearly recorded that none of the 3 entities that comprised the company were sold at all, factually the opposite.
Yeah that’s what con men do is convince their marks they are “geniuses” and then leave after the con with some INSANE excuse that even though the company was publicly liquidated with nothing since that his silence isn’t because the con is over it’s because he’s been asked to also keep quiet a deal with a public company for 6 years which is obviously illegal.
