Unresolved Fibre Cancellation and Billing Issue

I'm really disappointed at Vodacom. I'm writing this complaint for the third time here on Hello Peter, because i just got informed that I need to start the query from scratch and send the last complaint to a different e-mail address, whereas the only e-mail address provided on Vodacom's website for complaints is ***.

I've sent emails to Vodacom and called from the 15th of August 2021 to notify Vodacom that I'm moving out on the 30th of September 2021 and requested them to cancel my fibre account, till today they are still billing me for a fibre I'm not using.

I thought I'm doing good by giving enough notice and paying the August invoice but no one cancelled my account till today. And now I'm getting statements of huge amounts of a fibre account that I'm owing, how? When I've moved out and did notify Vodacom more than a month before? I've been a loyal Vodacom customer for more than 15 years. I can't believe that's how I'm treated today.

I need someone to cancel all my accounts and tell me what I should have owned if everything was processed on time by Vodacom.
