US Airways Dividend Miles (Pre-2005 America West merger) - "2,500 Bonus Miles with Every Trip" promo: receive any miles?

Promo 3669 was for 2,500 miles for each trip between 2/14 and 3/3/5. We flew on 2/14/5 and not received such 2,500 bonus. I do not recall saying that it took 6 weeks to receive it.
