Vodacom debiting me every month for a fibre month to month contract cancelled 2 months ago.

Cancelled my Vodacom fibre contract and Vodacom confirmed cancellation in January. Vodacom Fibre accounts advised that January would be the last invoice. I was charged another R899 invoice in February 2025 Vodacom debited from my account again. Now I have received another invoice from Vodacom fibre for March 2025 and they want to take another R899. Vodacom fibre advised a cancellation request was logged in January the last invoice was supposed to be end of January 2025 though there was an error on their side and they apologise. Cancellations then put me through to billing, now billing advising I speak to cancellations again as there is nothing they can do and now I start all over again just like the beginning of January and it is now 07 March 2025. Issue has been escalated so many times for the past 9 weeks and Vodacom are clearly ***********. I am left again with no choice but the log another complaint with ICASA and take the matter further. Vodacom ruined my Christmas and 2024 with their slow connectivity and *********** service. Now they continue to bill me for a fibre service I no longer have with them. I have moved to another provider Axxess who are much more capable.
