Bad service

We had a break-in at our house two weeks ago, the alarm was activated but there was no response. the day of the break-in ADT guys where on the scene only after I contacted them to inform them that there was a break-in and the alarm went off but they did not get the signal at their offices, they also tested the system and told us they will report this and a technician will be sent out. ADT has still not sent out a technician to resolve the problem and they did not even contact me. I tested the alarm last night again and I voluntary triggered the alarm a few times they only called me once after setting the alarm off after the last attempt. I am very disappointed in ADT this now makes it easy for the burglars to come back and take what is left in the house because the system is not operational, they are very tactless.
