Swearing on call, rude service desk

During load shedding my battery gets quite low so ADT calls me to confirm is everything is in order. This morning (30/01/2023) the service desk called me at 05:40 and 05:42 with an extremely rude awakening. The lady was clearly talking to someone while she called me and she was yelling, swearing and saying the person is not listening. She said "Sy P@es man, sy P@es".

This was truly upsetting. Then she called again at 05:42 and the same complaining continued until she put the phone down in my ears. The security arrived at my door and I told him that we were upset and the rude calls we got. He called them and said to her that she should do that. I appreciate his response, yet what happened told me of the standard security company I have looking after my home. I don't appreciate this excessive language, especially when I was being called.

I email ADT this morning asking them to end my subscription with immediate effect but have not heard anything back yet. I want my subscription ended Today. I have been a loyal customer for a few years now and this was just the last straw.
