Technician not willing to assist

We phoned ADT on 14/06/2016 to let them know that there is something wrong with our outside beams and that they need to do a maintenance check on our equipment. They sent out a Technician on 15/04/2016 and he told me that the beams needed adjustment and that it should be fine and we must test. I asked him if he is not going to check the cables in the roof as the DSTV guys did something to the cables when they installed new cables, whereby he responded \no it is too dirty up there\". We tested the beams and was still not working. We phoned again on 18/04/2016 and he only arrived on 19/04/2016, eventually went onto the roof and disconnected some wires and said if the beams go off again it means we need to replace them. We tested and it is still not working. We phoned them today at about 8:30 and spoke to Albert's Supervisor Vincent, who promised to phone us back with feedback. It is now 4 hours later and still no call. We stressed that someone tried to enter our yard last week and we need to get this sorted, Seems as if our safety is not important enough. Their motto is \"Always There\", but why do we struggle to get them to fix the equipment. So fed up with all the laziness "
