Extremely poor service

I was a loyal customer for more than 2 years, fixed contract. Then when the 2 years expired, I had a month to month contract. Vox came to my address and installed their hardware for fibre. I had no problem during the period I was on contract. In December of 2021, I gave notice to cancel as I had to reallocate due to my work and where I moved, there was no fibre yet. On the 1st of February my last payment was made to Vox, ending my notice period and my contract with VOX. I moved from that premises in January of 2022, to a different province. There are still 4 pensioners living at that address. About half way through February, the lady at the previous address phoned me to say there was a courier at their door, he is there to collect the hardware. She then politely showed him where the hardware was installed by VOX. "No" he says, he is only there to collect it. It must be ready for him to pick it up only. So who should uninstall the hardware that was specifically installed by VOX? I phoned the call centre and I explained that the pensioners living at the address where the hardware was installed by VOX, are not able to uninstall it and I live in a different province. I requested them to please send someone who can uninstall the hardware, just like they sent someone who installed it in the first place. I sent email after email, being ignored flat, ref. nr VOX***6. After the phone call in February, with no response, I sent emails, the first one around 7 March. I again requested someone to uninstall the hardware that they installed in the first place. It was at the same address, waiting for them to come and get it. But what does VOX do? Send me an invoice of R1210 for hardware not being returned. I emailed again, with same ref number and requested them to uninstall the hardware at the address that they initially installed it. I asked them to not debit my bank account as the hardware is where they installed it. No lies or April Fools jokes, on 1st April VOX took R1210 from my bank account. I am so very mad and upset, this is the worst service I have received in my whole life! By the way, the hardware is still where VOX installed it at. There to be uninstalled by them at any time.
