Robert,
Please post copies of any and all communications between you two.
Did he claim to have produced these snakes himself? If so, I live not far from Franklin and would be happy to take a look at his collection to at least verify that he has a real morph there. Since the only way to produce 100% hets is with a morph x normal breeding he should have no trouble producing the Piebald animal for me to see. I can pick up the "paperwork" at the same time and will send it to you for free.
Let him know of this thread and of my offer if applicable.
