No service

I am one of the unfortunate people that had to move to ADT when SSG merged/sold the business to ADT. I have had excessive alarm activations and I can understand that it is time consuming to go out every time but this i'm paying for. for. A Mr Gouws called me last week to ask if a technical person could go and check the alarm. Arrangements were made for Thursday 26th Feb. at a pre-arranged time. The technician was late and clearly had no respect for time keeping or to let anyone know. Arrangements were made for Thursday this week. This morning I received a notification that I will be charged for the extra times the alarm was activated. I have never agreed to anything of this sort, unfortunately I cannot always answer my phone when they call because of work meetings. I My only reason I have never reported the alarm is that I AM NOT ON THEIR SYSTEM?????? I am desperately trying to cancel but was told to email alwaysthere.i to do that. This must be changed to neverrespond.i as emails are ignored. hopefully someone at ADT will see this and respond.
