Service call cancelled

I had a service call scheduled to switch back to Uverse from Direct tv this morning. Direct tv turned off the service as scheduled . I called Att uverse and spent over 2 hours on the phone because the tech never showed up. They said there was a glitch in the system. Now I have no tv service and have to wait a week to reschedule and take off more work.  Who do I call to expedite this???? This is the bottom of customer service. What is wrong with att???? Please help.
