Vox - Not an ISP to be trusted

I have been a customer with Vox since August 2021, have been using them for my business. In December 2023 I enquired in having fibre to my home. On 1 February 2024 they sent me an email indicating that the fibre had been installed and that the router was on its way. I immediately got hold of them and told them that I did not want the service as I already had fibre to the home with Vodacom and that I had to give them a months calendar notice before I switched over to Vox. I cancelled the installation with Ndu ref number Vox***0. They also said that frogfoot had installed the fibre when no one came to my home, I already had fibre with Vodacom and they also used frogfoot. This caused a problem with my Vodacom service and could not go online, I was switching from Vox to Vodacom during the course of February, I had made so many queries via the phone, emails and app to Vox regarding this issue and every time they told me that they are looking into it and they will come back to me. End of February I was billed for the installation, I tried calling again to no avail. I stopped the payments to Vox and reversed the debit order they did for the installation. My business line which I had since 2021 was suspended on the 13 March due to the reversal of the debit order. To date I have been sending emails, making calls and no one is assisting me with my problem. What confused me as well is that Vodacom has charged me for a new service of which I already had a service with them. I am highly disgusted with Vox and the service I have received. I cannot run my business as I am dependent on the service.
