Unable to access email or reset password

I have an old email account with the @att.net suffix, that I still use a lot of correspondence.  

With all the changes recently as ATT disentangles its email from Yahoo, my access has stopped.  

I tried to remedy this by doing a password reset.  I used the challenge questions to verify my identity.  But after submitting them, the "progress indicator" just kept spinning and the system never went to the next step.  I assume it would have provided a temp password.  This state lasted so long that the ATT web interface prompted me to ask if I was still there.  

There is no direct email help support.  I'm here in the forum hoping for some assistance
