I don't think my Order is even updating... (Alienware 14 Delivery.)

I ordered the Alienware 14 on the 8/8/2013 (DD/MM/YYYY) It shipped on the 13th, and it's the 16th and I haven't got any order updates since.. Plus my carrier has changed from WWI to WUK, does this make the tracking website irrelevant now? I'd like someone to keep me up-to-date on this. Tracking site is currently the Walsh Western.
