Hi all.
In a nutshell, 2 weeks after completing a trip, MQMs have not posted even after 2 calls to the platinum line. What next? Keep calling the DL platinum number or some other tactic?

Details:
Two weeks ago I completed a ORD-AMS-DEL RT in J on a 006 paid ticket bought on the DL website. 3 of the 4 segements were KL and one (DL-AMS) was on 9W (via a codeshare announced last fall). All flights were DL numbered code shares. The trip was 1 week long and mid-week miles for the ORD-AMS and AMS-DEL segments had posted along with bonus MQMs. Two days after the completion of the last leg of the trip, I noticed that all miles had disappeared (and associated MQDs). I call the platinum line and a rather clueless agent said she'd send a note to the skymiles department. I checked 2 days after that and still no miles. I called again and this time the agent said she saw the miles on her system and that "they were just posting and should be visible to you in a few hours / end of day latest". This was 4 business days ago (this past Monday). Nothing on my account yet?

What is the best next step for me?

Thanks in advance.....
