I've known Ed for a lot of years, and if he doesn't have it in stock, he will find it for you (desite what is on his website or mail lists). Given a little time, he's never failed to come up with what I was looking for. On the few occasions when I didn't reach him by calling within his scheduled call hours, he always returned my call when he could. Might be up to a few days later, but he always got back to me. So I obviously leave messages he wants to reply to. Did you?
As Bill said, this man is spread very thin and no longer has time for chit-chat calls or email. There are folks here at GBO that have nearly as much savy about TC's as Ed does, so ask your questions here and leave contacting Ed mostly for buying or selling. Will sure help him out, and those wanting to buy or sell from Ed.
