Screen saver is NOT wanted

who do I reach out about the comcast/xfinity screen savers that goes on automatically & I have no option to disable it. I pay for 27/7 service  and should able to do want I want  with the service & NOT be told that if my service is on for so many hours unintended that the screen saver will be activated. That is not right telling paying customers how to they have to use their service  If I choose to leave my service on for 24 hours every day for whatever reason then I should be able to . Comcast/xfinity is not allowing me to do so. WHY not I pay for the service I should be the one to choose how to use it to my way of living Not theirs. Comcast/xfinity is stealing money from their customer when they auto active that stupid screen saver that s not wanted.
