I need Randall L. Stephenson (ceo of At&t) email.?

I need to contact at&t but when I used their online form they sent me an email about buying a laptop card when my question concerned my mobile phone. So not only did they ignore my question they used my information to sell me stuff. I can't find an email address for dept. heads or the ceo.
Update: CEO email addresses are out there because I found the email for CEO of Sears.
Update 2: Found it: randall.stephenson@att.com
Most big companies use the employee name. Since I knew the domain I guessed & found it. Yeah now he knows what crap his customer service is giving details to sales instead of helping.
