Data contract i did not agree on

I Had a cellphone contract which ended in July 2025,

I wrote to Vodacom telling them my contract ends and I don't want anything more because they normally continue with the billing even when the contract ended if you didn't send them an email.

End of July a lady called me selling a data contract I said I don't want any more contract because of my financial situation,

The lady go on to say no this is a month to month contract you can cancel it anytime

Because I was annoyed I agree as she said is Month to month contract

Come August I called Vodacom to cancel, and I was told to pay cancelation fees when I tell them I am on month to month they said no this is 24 month contract

I told them I never agreed to that so the guy who was assisting me said he will log escalation i should wait two days

Since August I have been calling every now and them it's stories after stories

On the last call they said the contract is canceled but the term is not hence the billing

Clearly Vodacom is not will to do this cancelation yet I have been telling them that I don't have money for this and when this account is not paid they switch off the network to that phone yet I completed the contract for that phone in July
