How many boxes were delivered. Sounds like you either just had a single controller delivered. If you received 2 boxes and one box is larger than the other are you sure you dont have a ccu hidden in a layer beneath the controller?
if you've just got 1 box then probably your order hasnt been completed. Contact support to discuss else wait to see if you get the rest of the order. The code usually gets sent soon after delivery of the ccu either same day or next day.
I ordered a controller with chrome cast and an additional controller. the boxes that arrived to me are the same size. one of them differs from the other box because it has the characteristics of the device. there are no funds and I found only the usb cable in both boxes.
on my account he says that the order would arrive by December 27th and in fact it arrived today. I will wait tomorrow to receive the activation code and answer to my question about the absence of the chromecast.
if you have a link for chat support, i would be happy to have it
@Camzsez11 : It sounds to me that you have just had 2 controllers sent instead of just a single controller and a premium edition bundle. The box sizes are different, the controller box has a picture of a controller on the top of it, while the box for the CCU including Controller just has the Stadia logo on the top.
Both boxes will have the same width and length, but the premium edition box or the founders edition box are taller by about 4cm or thereabouts.
