Slapgat attitude and shocking service

I took ownership of my new home in November 2015. ADT were the security service providers and I entered into a new contract with them. I am yet to receive the promised assessment of my ageing alarm system. In the interim I have been forced to upgrade using an alternative service provider and now ADT are refusing to send their technician over to activate the connection between my alarm and their response centre. I am travelling for a week and now have to leave my family with no armed response! I have tried in vain over the last two days to get ADT to understand my situation. Their response....we can only help you next week!!<br>
