Poor unapologetic service

I've been a loyal client since May 2022. I called Technical Department on 28/11/2025 as one of the zones are faulty. An appointment which was scheduled for 01/12/2025 and upon inspection by the technician, it was established the alarm system wasn't wired up initially when we upgraded in amay 2022 with ADT. I am still waiting for this issue to be resolved, still waiting for management to get back to me. I had to follow up multiple times but no resolution.
