The Zeplin Security Group no longer provides the quality of service it did in the past. When I experienced a problem with my system in May 2015, Zeplin sent employees who seemed technically incompetent. The employees installed a used key pad, and showed me how to use it. I was OK with a used keypad, as long as the system worked. I continued to use the system & pay my bill in advance, as I always had. It was only months later that I was informed by the owner, Mr. Fred Zeplin, that the system had never been repaired because parts were no longer available, yet I was being charged for the so-called "repairs" and "service" when my system was, unbeknownst to me, not even working. Mr. Zeplin or his employees should have informed me of the problem of a lack of parts, instead of showing me how to use a newly installed keypad as though the system were working. This is fraud! read more
