Welcome and thanks for your post @84sparky84
I hope you're making the most of the Christmas festivities. I am sorry for the problems you're having redeeming your Xbox Game Pass. When you placed your order originally, what date were you given for connection? You'll need to wait for 14 days after service activation before redeeming the Xbox Game Pass.
If you're still having problems after that time, feel free to post back and we'll be happy to help you out.
All the best,
Robbie
