That is well understood. I think many here have lost money and can identify with you. I am less concerned with the morality of the issue, but you do need to stick to the agreement.But their mistakes did much more damage to me than just that and due to my desperation that moment I had accepted an agreement much less than I have lost. And I am not talking about profits I am talking about my investment only
If you feel you were unduly coerced into the agreement, that would be grounds for voiding the contract, but you should be willing to give the money back that they gave you.
On the other hand, if the agreement did not include a confidentiality clause, then you are free to post here. In either case, you need to take a stand.......either put up your case or delete the thread. You are sitting in no mans land at the moment where you are potentially in breach of your agreement but not actually giving the details. That is a no win situation for you.
