The Place where Customer Service goes to die

I submitted a cancellation for my home fibre connection with Vox on 01 December 2022, and planned to move over to RSAWeb from 01 January 2023. Vox subsequently stopped my service and I was ready to start with the new provider. As it stands, I can not get my line operational with the new service provider because Vox has not bothered releasing the line. I run my business from home, but do not have internet access because of the incompetence within Vox. I have tried to get my line released, but I am simply transferred around with no care. In essenece, I am being held hostage at the moment and I do not know what to do. They are literally not helping at all. I was on hold today for an hour with no response.
