WLE900VX 5Ghz card not working

I’ve just received my Omnia and it appears that the WLE900VX card supplied doesn’t work.
The PCI light for the card is off and the GUI shows no sign of the card.
I have tried swapping the card in all 3 PCI slots, which didn’t work.
I have taken the card out and put it in another Omnia where it also isn’t recognised.
So I’m convinced that the card is dead.

Does anybody know how I contact someone to request a replacement?
