Your best bet is to private message one of the Comcast support people, ComcastJoe, ComcastDaniel, ComcastAndy and bring their attention to this thread.
Just for your reference, I posted about a missing Doctor Who documentary http://forums.comcast.com/t5/XfinityTV-Website/Missing-Doctor-Who-Documentary/m-p/2020643/highlight/true#M30857 and after 90 days and no response I private messaged ComcastDaniel who finally got the problem fixed so be prepared to wait.
