Every station shows things not related to their brand. One can cancel their subscription, but it will not effect programing. I just watch shows I do not care what channel it may or may not be on. If space is showing a war epic documentary I will watch it on space. If the food network is showing gardening tips I will watch that show if it interests me.
Getting in touch with the station and explaining your frustrations with programing may result in a program change, especially if 1000's of people say the same thing.
I have a photographic memory, trouble is most times the lens cap is on.
