ADT is giving bad customer service

i currently have a rented alarm system that started giving issues after about 5 years of working without issues.<br> i reported the alarm system to ADT and the consultant did not seem to have any clue of basic troubleshooting that was the first issue.<br> i eventually asked for tech to be dispatched to check the alarm and found that the system is faulty . The technician decided to disconnect the alarm complectly without consulting with me and left a replacement bill of R 8 000 without informing me who needs to pay the bill since this is a rented system. <br> <br> i am now without an alarm, before the technician came to my house i could use my alarm and had to reset it once a week but now i am complectly exposed . i called the call centre and i was told i need to wait for the technician to load the `Job card on the system and a week later no call from ADT and all they told me was we will send a patrol vihicle to be posted close by which does not mean anything at all to me.<br> <br> i used to get a good service `from ADT and now i wonder what changed.i called ADT again and i was told now that the Job card has been loaded on the system and they will send an email to the Technical manager to call me tomorr
