Inefficient, slow customer service

I moved into a home with a security system but had to have the system replaced. I purchased an additional sensor for the garage and requested that the technicians have assign a separate zone for the garage as they connected it to the kitchen/lounge area. I was informed that the panel I had was limited to 8 zones and i'd have to purchase a panel with more zones, I then asked that the passage be removed as a separate zone and that the garage replace the passage. The technicians had arrived relatively late for the installation and the reassignment was not done, i assume due to the installation being completed after dark and having to knock off. I had assumed the reassignment would be done remotely/at another time.

I called the call centre to follow up on the reassignment and was infirmed i'd have to pay R650 which i refuted as i had given the instruction prior to installation. A lady by the name of Lerato agreed to have the reassignment done at no cost and advised on 19 Jan tha an instruction would be sent to the team responsible. I followed up on 21/2 and was informed that my query had been assigned to Ridwaan who has since left ADT Security. I was then informed that Lerato would call me again to discuss next steps - it is 27/2 and still no word. Really disappointing service!!!
