ADT ripping clients off

Before you take ADT alarm system in Soweto think twice, I was forced or manipulated to take ADT 3 year contract, because it a well known Security company which is now in Soweto but the service is questionable and not so great firstly you'll never see they roving around the area only when the alarm traps they'll come but 2 hours later by that time I've already secured the area myself but in a case where there's really danger I'd be dead "talk about safety" I had to join another security company to assist ADT as their visibilityis at a 0 in the EXT 44 Protea Glen. Now their alarm system is malfunctioning now and I notified them I was told I still had warranty and the technician called and told me I had to pay R 400 and something because the malfunctioning battery was caused by Loadshedding and how is that my fault, Am I the one switching on and off the electricity. I pay them monthly for a mediocre service and now I have to pay the same money I pay monthly. Just come and take your alarm system cause I dont see the point of it.
