Technical support is pathetic

We installed new beams in August 2019 at great cost. Ever since they were installed the beams get triggered for nothing. They told us we need to bypass a zone, as maybe the unit was faulty. It helped for a month and then it started in a different zone. The beams get triggered 5+times a day whether the wind blows or not. I have called multiple times. they do not schedule visits. The technician and his 3 trainees hung around in December and basically nothing changed. I have been calling again, 2 weeks and still no technician, no call, no visit and not able to arm the beams because they charge as for excess call-outs!!! I was told to bypass the zone that activates the alarm and tried doing it over the phone only to find out that zone does not exist!!!!So made a big investment for an alarm that gets activated daily!!!!they asked me whether there was something in front of it. But if we are away and the alarm gets triggered every 30minutes, how can that be possible? I am so fed-up because no one seems to know what is going on and each time they bypass a zone or a beam, it means it is faulty so the newly installed beams don't work and we paid for something that cannot be used?? And basically they are not sure what is going on...no wonder ******* have a field day.
