Business ProfileforSentry Security Agency of St. Louis

I hired this company to put an alarm system in my parents' home. They installed the system. When the system was checked, the office claimed it was working, but it didn't appear to be working on my end. There were several contacts that weren't working, zones that were switched, They have stuck electrical tape on the wiring and gathered it in bundles. The panel box is barely hanging on the wall. I called them and told them about this; they sent an agent out and took pictures. I heard him say to his supervisor that he understood why I was upset. But they didn't fix it. When the VP of the company called, he didn't acknowledge that anything was wrong. I referred to the pictures taken my the technician and he didn't acknowledge that they existed. It looks as if wiring in the home has been damaged. That's what has been electrical taped back together. It's been about a week. I have not given them any money yet, and I didn't sign any paperwork because the tech didn't bring any contracts. I don't want them back in the house because the three times they have been here they have damaged the house.
