No service

I had a ADT Alarm installed in my house 10 months ago by an agent which by all standard did a very bad job<br> Not finishing all the detail work etc after a complaint that I no longer wanted the agent in my house ADT said they will <br> Handel this which they at first did since then however I have had technical issues with my alarm 5 calls have now gone unanswered .... Can't tell you who's gives me the worst service 5 calls 4 months no service!!
