Vodacom frustation

Hi... My vodacom wifi contract was expiring at the end of August 2020 and i had to give 1 month to discontinue with it... I gave notice accordingly on the 24th July 2020. I was told by the cancellation consultant that it was done. I even asked him if he was sure as i didnt want to get blacklisted for it as i am unemployed at the moment. He assured me that it was done. On the 2nd of September i realised that the sim was still active and since then i called the call centre numerous times. I keep getting told that the matter has been escalated to a higher management and that i will receive feedback from vodacom... Its now the 8th October and my money has been deducted from my account and i still havent received feedback. I visited a vodacom outlet today and got told that the sim is still active and that i need to contact Elite Mobile... My contract was taken out with Vodacom so i dont understand.
