Do Not care about Customers safety

After signing up with ADT at the beginning of August, the sales consultant said that they would send a technician to us to set up another sensor at a door and an eye in the lounge area that is not covered by the current one. Also they did not really know how our alarm works and said they would get us a manual. As of today I am still waiting for the technician and the manual I went online and downloaded myself. I have called ADT in the meantime but after I got cut off cause my contract ran out, they didn’t even call me back. Also the person I spoke to said my emergency button is not working and neither are my panic buttons. So, if the security of their clients is their no. 1 priority then why haven’t they contacted me regarding all these matters.
