Faulty Equipment

ADT installed an alarm system to our business property recently. Since the unit was installed we were experiencing issues of which one is a recurring false alarm signal being send to the call centre. This causes unnecessary call out's of the guards & unnecessary trips which I take to check that the building is unharmed which are both at my expense! I would like ADT to send a technician to correct the system errors asp. I've logged numerous of complaints directly with the ADT team before and have not been assisted for 4 weeks?
