I have had an installer that IMO was good with the physical bits as in wiring, C4 screens, wall mounting TVs, lighting installations etc. But when it came to the actual programming I feel that its not complete. Right now I do not feel the system is working as it should. I have been trying to call the installer for a few months now without any luck. Can I get someone else to look at it or does this system now have a password/lock done by the existing installer? Can I get it finished by someone else and then if this installer ever comes back, I can give him access again to my setup?
