Poor client services from Vox

I am a client for VOX for almost 2 years uninterrupted. In February 2023 my data/vibre line at home was not functional. I firstly tried to report it telephonically to Vox. What a battle to get through to them following all the prompts. I decided to communicate the technical problem with my line via email. They responded within an hour with a ticket number and that is where it stopped. The following two months was just emails on emails without anyone responds. I threaten to cancel my contract, that did not worried them. I reversed the debit order amounts they deducted. Still no response. I thought that will prompt them to phone me to check why the debit orders bounced, they didn't care. Cancelling the contract, no care at all from them. Eventually I received a call from Amy, very helpful and the next day a Technician was at my place. Power supply was faulty. Problem solved. It is now one week later, services down again. Do I need to explain the nightmare to get through to them? Lastly I eventually again get through to them. An account for the two moths that I did not have any internet connection is outstanding. The answer from Neeresh in accounts, we do not bill you for usage, but for access to our services. Neeresh, VOX I did not enjoy any access to your services for two months. Why do you bill me for services not rendered.
