I had this happen on MCI-DEN. Got EasyUpdate message five minutes AFTER I boarded to indicate my UDU had cleared, but F had already been filled. Went out to talk to the gate agent, who offloaded me, and then realized that F was full. While I was sure she scanned me back in, she must have forgotten, and the miles never posted.
Long story short, it took three calls to Mileage Plus, and two emails to 1K Voice to get the credit posted. Do you still have the ticket for that flight?
