TIVO/ROVI new Guide Data unrelaible

I have a 4 tuner TIVO Roamio. I have issues with no guide data on some of the channels. I have filled 3 tickets with their channel lineup correction team. I found even more channels with no guide data so I will have to file another ticket in addition to the three previous tickets. WTF is going on at TIVO since ROVI has taken over.
