Terrible service from Vodacom fibre

On the 1st of March 2023 I cancelled my Vodacom fibre as I was moving to a new apartment and they told me I would have to get a whole new contract for the new place. 25 May 2024 I realised I was still being debited for the fibre I cancelled. 3 June 2024 I called them and they said whoever my cancellation was handed to didn’t cancel it, though they see the request to cancel. They said they would investigate and send back my money in 7 days. With no feedback from them for over 2 weeks I called them again, only to be told the investigation hadn’t commenced and the contract was still not cancelled. I called the cancellation team and cancelled, even received confirmation. A day later I received a call from abrasion telling me that someone whose moved into the apartment I had vacated wanted to used the fibre, therefore they would remove me and link that person. 25 June,once again I was debited for the fibre I cancelled, mind you, I’m yet to be charged an early cancellation fee. No one has called me back. It’s frustrating that I am continually charged because someone failed to do their job of processing the cancellation request. Whenever I call them I get taken from pillar to pillar 😡
