We accepted one of those terms. The terms were withdrawn after we accepted. The $%&@ off and refusing to talk are responses to that. You can offer us whatever you like, but we do not believe that a single offer you have made is genuine. You can either find a way to convince us you're making a genuine offer (I have no idea how you could do this, but its conceivable), or you can accept an offer we make. Throwing more offers that we don't expect you to actually sign is irrelevant.
Also, you might want to drop the whole 'we attacked Legacy not CSN' talking point, its one of the sources of our grievance with you, just makes us mad and less willing to talk.
