Xfinity Web pages

For a company that provides internet services the web pages for Xfinity are extremely slow and often seem to fail.  All I was trying to do was to view my full bill online.  The email notification of my billing has a link supposedly to view one's bill but after waiting minutes for pages to load, you don't actually get to see that bill, only the total amount.  The next step to try and view the bill ends with the web site just quitting while loading another page.  Note that I do have Xfinity internet services and they test out at 900 mbs and I am on a very powerful desktop computer.  It really seems that it is the web pages that are 'defective'.  This suggests that switching to paperless was a mistake!  ;-)

Note: The page I am typing this on won't let me select a Category or Topic.  I can briefly see the choices but can't select any since that sub-window closes when you try to access it.
