ADT alarm is faulty from the time they installed

We had a perfect working alarn but decided to opt for a security company for the safety of our family .We contacted to ADT one and a half months ago but from day one we had problem with the system and their service.Besides all the emails and calls to the call centre,where we speak to ppl in other provinces who don't give a damn.My final straw is today 10 Dec where the alarm just triggered and the alarm went off and won't work due to contacts not installed properly.We called the technician Mark who said we must call Vaughan the manager.We eventually got hold of the sales rep who told us he did put a urgent request for the technician to come out and an email to *** one came .I then watts ap Ashley who said Vaughan is in church and he gave me an office nr. Which would only ring ,by now its pass 5 pm.They are making us like fools and we don't appreciate it.The alarm is not working at all as well as the beams.Melissa from the call centre advised she will get a technician to call so we could by pass the kitchen contacts and get at least the beams to work.We are devasted,stressed and very disappointed as the product & product is faulty.<br>
