I wish you had turned to this forum years ago, and long before you grew so frustrated. I am a long time user of C4, not a dealer, but I can say that I have not experienced any ongoing issue with my systems (multiple houses going back to 2008) and I have lighting, sound, camera’s, AV, security, blinds, etc. I would suggest you give one of the dealers on this forum a chance to address your issues before spending the funds to remove or replace it.
