No regard or feedback about bad service received

On Saturday I had an incident at my residence where I pressed my panic button three times and after four hours only did an armed guard show up, park outside my house and drive off again without even checking my property. The whole point of armed response is for them to check on your safety especially when a panic button is pressed. This is not the first time it has happened and when I tried to complain last year I also received no feedback from anyone in management. I then proceeded to log a complaint but to date I have heard absolutely nothing back from anyone from the company. I subsequently am cancelling my service with ADT and its just so sad that such a big company, one of the biggest in SA has such pathetic call centres, management teams and poor customer service.
