If you click on the "Track Now" button it should take you through to the couriers website. In my case it was DPD and they haven't updated to show my proper tracking yet, but definitely DPD.
Thanks for the response.
I had already tried that and mine is taking me to a site called Syncreon which I assume(d) is Apple's internal logistics partner but I could be wrong...
Oh well - I'm sure mine will turn up at some point.
Thanks again.
