Vodacom Contract Cancellation Nightmare

I am extremely frustrated with Vodacom's cancellation service. I contacted them on three separate occasions to cancel a contract, I went instore and was advised to cancel via 082135 which was done 14 November 2024, 1 December 2024 and an email sent to cancellations 24 January 2025 as I am still being billed. No one responds to advise or update me on the status, as I am already out of contract and wish to cancel yet am still being billed. This is so frustrating!!!
