unable to pay bill online for a few months - anyone else having the same issue?

I get a message saying  "We noticed that your account doesn't include TV service. If you're interested in a TV product, please visit directv.com.  To manage an AT&T product, please log in to att.com. This window will log you out momentarily.  

I have changed browsers, cleared cache/history, etc.  

I talked to a tech support person who said to check back in a couple of weeks.  Still no fix.
