No response to alarms and phonecalls

We had a burglary 12 days ago in which ADT responded well BUT SINCE then the most shocking service ever! Firstly it took them 9 days before they even attempted to contact us regarding our request for outside beams. Secondly we had our alarm activated without any response at all from ADT. When we reported this matter they promised to write a report to the technical department and come and check their faulty radio. Because strangely enough the radio sometimes works during the day when I tested it. Twice in the past week we had an activation wat 1:05 and 1:30. Sunday night we had to wait more than 9 minutes for a vehicle to arrive. We had someone responding to our complaints with a phone call, but still no one coming to see why their radio was faulty. Last night before we went to bed we requested the technical department to come out but they said they might only come 27/7. Tonight we phoned four times. The fist time we got cut off, the second time the lady answered and said they would send a vehicle,but and hour and a half later no one came. When we phoned again there was no answer and the fourth time we got through to Port Elizabeth! We are clearly paying for a non existent service
