Faulty/unreliable alarm system

Since having my alarm installed less than a year ago, I've had regular problems with false triggers by the product.<br> Several months ago, this was supposedly attended to, and resulted in the main board being replaced.<br> <br> Last week, (2 weeks after originally requesting assistance) the technician (Vincent) came and indicated that the sensors triggering the alarm were too sensitive and supposedly made an adjustment. Interestingly enough, a few hours later, another false alarm triggered.<br> In addition, the siren doesn't go off when the alarm triggers, and only a long beep sound comes from the keypad. This was put to his attention, but clearly nothing was done.<br> <br> I again called to complain and have a technician sent to sort it out, and nearly a week later, no response.<br> <br> A few hours ago, I've called the call centre to speak to a senior person. After a while of listening to music, I'm told that the manager was busy and would return my call in 15 minutes. Of course, I get no response.<br> <br> So I've paid thousands of rands for an unreliable alarm system that, besides a monthly monitoring fee, now just costs me more money in petrol, wasted time and unnecessary panic. Really???<br>
