xfinity is not updating tv show descriptions on the guide

For over 3 months Xfinity has not been updating the descriptions of about 1/4 of their shows.  They show only a general description of the entire series.  Just tonight, during prime time, there are 3 shows on ID and 3 on TLC that have not been updated.  Accessibility has claimed that they are not getting the updates, which 13 networks I contacted said is not true.  Now both, Accessibility and Xfinity Customer Relations won't even answer my emails.
