I had a similar problem. I had originally asked to put my delivery on hold for the month of July because I was travelling. When the game got shipped out in Aug, mine wasn't delivered because S&L didn't receive shipping instructions from AG. I called S&L and they found my game... I got it a few days later.
I was going away for July as well, but I didn't trust Academy Games to hold it properly, so I just called Snakes and Lattes directly and asked them to hold it. When I returned to Toronto I went to their location to pickup the game (and Saloon Tycoon which they also held for me).
