Website and App

I am completely unable to use either the website or the app with my account. Any tab that I click on in the website loads for ages and then "Sorry, this isn’t working right now
Please return to My Account Overview while we resolve the issue." Every time I try to get into the app, I log in, it says I've successfully logged in, but that "Access not Authorized. You signed in successfully but you must be an Xfinity user to enjoy this service". 

This is all while doing this through my Xfinity WiFi (which is somehow working great). I am a user. I just can't access anything
