This just happened to me 2 weeks ago. I bought a card and the DC says it was delivered but I never got it. I waited for almost a week hoping that it just got misplaced in the mail truck or something, but it still hasn't shown up. I called my PO and gave them my information, and I'm still waiting for them to call me back. Good thing it was only a $20 card.
