ADT - Zero customer service

On the 23rd Feb 2023 I wrote an email to ADT to cancel my armed response which I have had for more than 20 years. I received an auto-response but then heard nothing again for a week. I called their helpline on the 1 Mar 2023 to ask them why I have no response yet and why they have not conformed the cancellation. The agent, Motsepe, told me that it had not yet been assigned but should be assigned by the 3rd March 2023. I then wrote to Erick Becker, who is the branch manager for Pretoria East, he never acknowledged or responded to my email. Today the 7th March 2023, even after resending emails to the relevant ADT departments and the Branch Manager again, I still have no response. Clearly they have no idea about customer service.
