Xfinity DVR Cancelled our recordings for no reason.

Shows scheduled to record this morning recorded fine. But shows scheduled to record this afternoon and this evening appear to have a red circle with a line through it. These shows appear to have been canceled by Xfinity because we have no conflicts with having too many shows scheduled to be recorded. We have been waiting for a call back from an Xfinity representative for over 45 minutes in hopes they can tell us this in an internal problem THEY are trying to resolve. We tried to reboot our system. We even unplugged our TV. Still did not resolve the issue.
