poor service

Abt 7 years ago I installed ADT at home not sure why I stayed with *********** lot of idiots , I guess it was because of convenience . The few times I have called them in the past I received no or very delayed services . About 2 weeks ago my kids were home alone and my son accidentally set off the alarm . I did receive a call from them so I called in and they advised that they did not receive a signal however they can send a tech out at a charge . I was not happy and requested a manager call me , that same night I pressed the panic and they called a few mins after so I asked the lady for a manager. To date no response. Today my home was broken into and valubles to the value of abt R25000.00 was ****** & I am not insured.coincidentally I was behind the casual adt response vehicle that arrived at my home abt 20mins after alarm went off. He advised that his callout was cancelled, they did not even call me. I got a call from a manager insisting his van was on the scene earlier then I claim.He is currently investigating. I pay a premium and had they responded immediately then they would have caught the ******* and prevent other ******ies. Please think twice when dealing with ADT .
