Lack of service

In January 2016, I installed an alarm system with ADT Security. From the onset I had reported that the alarm is faulty as you would bypass it and it would not go off. After several attempts from my side to alert them to the problem they finally sent technicians on two separate occasions. The system was still faulty. On the 5th of April I reported the matter to a lady by the name of Mmatsatsi from their response team, she conferenced the call to their technical department and I was promised to receive a call from their technicians when they will be able to come and get the system up and running again. Unfortunately that call never came through. This morning I reported the matter with an intention to cancel the contract with them, I spoke to a lady who advised me that the calls are being recorded from the customer service department and she conferenced the call to the technical department, which again I was left hanging for more than 20 minutes on the phone without anyone attending to the call until I finally gave up and hung up the phone call. I am truly disappointed as I have entrusted the company with my safety. I would like them to either refund or fix the problem<br> ***
