Can’t watch on demand! Error message!

I set up my Contour 2 boxes on 12/21/2020. Unfortunately when I go to watch on demand there is an error message and I can’t watch anything it says, “This channel is not part of your subscription”, which is not correct. I called technical support and after 45 minutes on the phone trying to resolve the issue they said that tier 2 would work on it. I check constantly and still not working.I had a lot of shows on my previous box that I had to get rid of when I got the new box and now I can’t watch those on demand it’s very frustrating.
