Uverse Guide for PBS shows is incorrect

I'm a big fan of PBS and the evening NewsHour.  Something changed this week to the PBS schedule but the Uverse Guide hasnt been updated. For several weeks now the Uverse Guide has listed childrens shows throughout the day but the station was actually running science shows (we would schedule 'Sesame St' for the kids but get a recording for Nova). No big deal. But as of this week the Newshour show is still listed in the Uverse channel guide but BBC is actually being shown. Is there a way to report the 'errors' to have it investigated and hopefully update the channel guide?
