You're wrong on several points, JB.
First, no matter what EarnestDD posted, you would say it's not proof. He gave you an incontrovertible avenue by which you may prove or disprove his claims (namely, calling Turner Stone yourself). You are simply afraid to face the fact that he is telling the truth.
Next, people will say a lot on the phone that they would never put in an email. If people reasonably expect that the call is not being recorded and the conversation will be deniable after hanging up, they may run their mouth off. With an email, they KNOW they will be held to what they type in the message. It's sad that some (many) see this as perfectly valid behavior, but it happens all the time.
Now, why don't you just make that call and settle it? Oh that's right, I already said why above: You are afraid Earnest is right.
IMO.
