I tried calling twice, but nobody would help me with my issue since I don't have an active at&t service associated with this account.  Spent over an hour on the phone and could not even get anyone to look at it since it is just a "free" email account.  Is there anyone here who can help?  I am positive it has to be something that is disabled on the back end, since I have followed all of the at&t troubleshooting steps on my end.
