BAD SERVICE

So finally after 2 months my alarm was installed half way, the passives were put on the wring place, AN OLD ALARM SYSTEM WAS INSTALLED, probably one that was removed from another property, the technician was shocked to find out when I told him that the alarm system is old. He said he didnt know I mus get a new ALARM system. Didnt get another panic button. NO ONE is getting back to me management, admin, technical all suck at ADT oh and the cherry on top we had armed response sent out because the alarm was triggered they came out 15-20 mins later. Oh and Shayna De Bruin from Installations is not answering my calls
