We've been TELSCO customer's for 15+ years and as will happen technology ages and needs to be upgraded at times. This was the case earlier in the year and at their recommendation had a new system and keypad installed to insure continued coverage and monitoring. Unfortunately, after the upgrade there was an unexpected issue that while not jeopardizing the system itself did make for a persisting annoyance. Although it took a couple of attempts I can't speak highly enough of TELSCO's commitment to look after their customers and in particular Kristin. She was always very prompt to reply, took our concerns seriously and treated us with the utmost respect & consideration for our time. I can recommend TELSCO with absolutely no hesitation.
