What area are you located in? At the top left of
the MS Support page you are using does it match the
country you're calling from?
In the U.S. both the (800) 642-7676 and
(800) 936-5700 numbers worked for me but
there are other numbers outside of the U.S.
If you're in the U.S. and calling from work it's
possible that certain 800 numbers are blocked.
============
More information:
I called the number on the support site that the article in your link,
linked to: 800 642-7676. There was a recorded message that said the call
could not be completed as dialed. >>
