Return Label

I got an email from Xfinity with a link to a return label for my trade in Phone. But when I click on it, it brings me to an empty page that is also empty when I klick on print. Can someone send me a label that actually works and I can print. 

I already regret switching to Xfinity from T-Mobile. For the past 24 hours they can't get my phone activated and the number switched over.
