Digital phone features not showing

I have had the digital phone since early September.  As of today I am not able to activate or deactivate any of the features that are activated or deactivated online.  No help from ATT even when I have spoken with customer relations, etc.  I have even been told may take 2-3 billing cycles.  I wish that had been disclosed when I dropped by analog line for the digital phone.  I even bundled with other services and nothing done.
