Zero sense of urgency from ADT

Have been a client of ADT since 2012,their service is poor&have no sense if urgency.They only react when you post on Twitter, 2 weeks still waiting for them to send a technician to come and install a panel. Zero sense of urgency for a company that is supposed to be providing security to its clients. Alarm has been faulty since Sept&now they are billing me for responses exceeded and yet my alarm is not working. They have left us vulnerable to break ins and they never respond to emails. Worst service ever
