I had one stay and recieved 1005 miles. Delta said it was Hilton's faullt. Hilton said Delta deducted the 2010 miles in February. I contacted delta again and included the message from Hilton. I got a response indicating that someone at Delta doesn't know how to read because their response was related to the current Fly Drive Stay promo.

I sent them another message a few days ago telling them, nicely, to please read my message again and deal with the problem I was actually having...no response yet
