Hello @Pinkham ,
Welcome to the community,
if you click Manage at the bottom of the app, you should then see plan bills and devices, try clicking on that, I believe that you should find the documents there.. When you upgraded, you should have received confirmation and be able to click on it there as well. If you have not found it, check your spam/junk folder.
To contact EE customer service dial 150 from your mobile phone or ring customer service for free using web based app or another phone: +44 800 079 8586 or +44 800 956 6000.
