Safe Touch Security Reviews

I have had SafeTouch since 2012 with few, if any problems until now. For the last few months, the keypad has an alert that one of the zones is not working, which causes an incessant beeping. The resolution offered was to disconnect that zone until someone could come out. First tech "fixed" wrong zone, second figured out which "zone " was bad. Now my alarm has gone off in the middle of the night, twice, saying that a zone has been "tampered" with. Out of concern for my neighbors, and our sleep, I am not alarming my house. The senior tech that came out today feels that the system is antiquated and needs an "upgrade". He is probably correct, but informed me that the "lifetime" warranty has expired. What I love(d) about Safetouch is the immediate human response. Now I am told that my intercom is "garbled" and I have to be contacted on the phone. I am currently looking at alternatives.
