Would love to hear your five point plan on exactly what you're going to do about it.
I have no idea why @tt2000 is copping any heat on this at all. The buyer was not disclosed until well after the deal was meant to be completed, so they got their confidentiality, and the deal still fell through.
If they had have disclosed the buyer at the start, then perhaps there would have been some due diligence at the very start and no one would have lost any money at all.
