Doing more harm than good!!!

<p>I received a visit from an ADT rep to review the current system I have in my home and gave me a quote on add-ons for my current alarm that was in a working order at the time, as I've been using it for some time. A technician named Adriaan came out to my premises to do the installation for extra passives. I noticed one of my beams that use to be in a perfect working condition was no longer working and I phoned for Adriaan to come out again to fix the problem he obviously caused, he did resolve the issue I had with the one beam I complained about but at the same time caused even more issues with my other beams that was in perfect working condition. He did a permanent bypass of some sort now and just messed up everything and spun me a story about power supply to the beams and I don't what not - I need this to be sorted out as soon as possible - as I've did refer this matter to the rep that helped me, which he referred to the technical department - I've had no response from the technical department, and Adriaan doesn't return my calls. This is looming now for a long time now and I'm fed up. </p>
