My Amex SPG closes this week it will be interesting to see if points post. Points from June posted no problem from both of my SPG cards (bus and personal). I am in the same boat as you though I haven't called them yet on an internal transfer. It has been 7.5 business days and counting. I know they are probably slammed but disappointing.
Edit: Oh and don't believe Amex front line CSRs, I love Amex but the CSRs seem to make stuff up. I had a retenion bonus post in July (I forgot about that) and it posted within days of my hitting the spend. Amex is most concerned about returns on such minimum spend and my points posted even before statement cut.
