Cancellation Error ONCE AGAIN

I've been calling in since August to ensure that the contract that's coming to an end does not roll forward on a month to month basis. I was assured when I called in that the notice has been filed and that everything is in order and the last payment due today 31 Oct 2023. I called in today to just find out if the services are being cut off tonight only to be informed that the cancellation has not been processed and I will be billed for another month. I am not willing to pay for another month and cannot deal with Vodacom's incompetence once again! I had a nightmare experience with Vodacom when I processed a premature cancellation and now I must go through the same nightmare again? I'm tired of this company!!! The consultant I spoke to gave me a different number for which a cancellation was processed in September. I do not know what number that is when I only have this contract with Vodacom.
