Paying for no service

We experienced electricity issues at Newlands and it came back with a high voltage, so a lot of appliances were affected. The alarm system is now dead and hasn't been working since the first week of April. I called ADT and they informed me that a technician will come, I must say that you will never see a van patrolling, knowing well that the area is affected by power outages. Anyway, I am informed about a call out fee and when the technician was supposed to come, we were load shedded. He then said he will call again later. That never happened. I had to call them again and I was informed that the appointment will take place on the 21st. I expressed my frustration of paying for a debit order for a system that is not working. On the 21st, Vuyokazi from ADT called and informed me that the technician has a car problem and that they will call later to reschedule or check if the technician can come. Today is the 23rd, and they haven't said anything to me.
