Hence I would be surprised if the DL twitter team can see more than whether you have a Reserve card tied to your account. YMMV but IMO you need to contact AmEx (try the customer service number on the back of the card and ask for a human agent) to ask if there's a problem.
According to AMEX ...
"We do not have access to the Medallion Qualification Miles as they are issued by Delta directly."
This seems to go against what others are saying, so I am indeed quite confused.
Regardless, I have one day to wait until the 4 weeks has passed since my first transaction, so no one says they can do much until then (as MQMs can take 2-4 weeks to post).
