ADT is ***********

I have an ADT alarm system. It has been sending a false panic signal to ADT for the most part of this year. ADT has sent technicians to have a look at it several times and they have not managed to sort it out. The last technician who came to my place, Lawrence, was even more useless. This was last week Tuesday, 22 December 2015. Lawrence did not do anything. He haD been sent by ADT before to come and fix my alarm, so I do not know why ADT sent him again when he has clearly failed to fix the same issue before. Lawrence came to my place and just told me that I need to change the alarm system at my own cost, there is nothing they can do. Why would I change it at my own cost and yet it is ADT's system that is faulty? He then said, standing at the door, that I will have to talk to the regional manager, Wimpie, about it, but he refused to give me Wimpie's number. He said he will talk to Wimpie and Wimpie will phone me the next day, 23 December 2015. Today its the 29th of December 2015 and Wimpie has not phoned and the alarm keeps going off sending a false panic signal to ADT. WHAT AN *********** BUNCH!!!!
