Extremely Poor Service

I received extremely bad service as a client from ADT. You hang on for long periods of time, before you are attended to. An additional service agreement was signed with them on the 10 August 2022. Up until now we are not active on their system, because they are delaying to send out a technician. Our computer lab is exposed to the risk of safety and security issues. You ask to speak to their seniors, the call agents put you through to an escalation department that does don't allow you to get through. You get cut off in the process. Basically you don't get through to them. I am Mr. Louw, Principal of Cavendish Primary School, and my number is ***. I'm frustrated with their service. Please intervene
