"I'm a FFGO shareholder and a piece of those assets belong to ME"
Actually you don't have any "assets".
You bought FFGO shares. NMGL distributed those dividend shares to Western (not you). FFGO then closed all their business licenses, went out of business, and was revoked (they don't have any liability to pay you anymore).
Western has never distributed the NMGL shares to FFGO shareholders.
So you don't have any assets.
You say you do? Fine.. try cashing them out.
