Installation team drive like they are on kyalami race track

On the 12th January we ha an ADT vehicle which was clearly an installation vehicle cut us off not once but twice while driving as well as another SUV in front of us. I called their number to lodge a complaint and had the lady tell me she will get the manager to call the next day as that department was closed already. Well needless to say that i got NO call back and the driver got away with it scott free. If your guarding services are as good as their installers driving skills i am glad i did not opt for ADT as a supplier!
