If it is just related to a Mac that was barred, try another Mac. If there is a bigger iissue, you will need to e-mail support directly at

There's a chance Crazed or Marley may be able to help, but I would send the e-mail (along with your particulars, like e-mail used for the order and the order number) to get the ball rolling.
