Until I see where the 3 million shares are, I consider this a scam. Why aren't you showing us your portfolios?
There's no way to sell 3 million shares any time soon, so I'm not super concerned at this point.
Having said that, this seems like a very simple issue to resolve. Send the account info to Burnside ASAP.
I am not saying they sold all 3 M. My guess is 25% or 750 000 shares.
