Being Billed after 2 years of

I am not happy with Vodacom. I had a sim contact in 2022 and the term was 2 years. I was on a call in 2023 with them and asked them to cancel and they said they will cancel it on my behalf and I relaxed knowing that my contract is cancelled. Now in 2025 I am receiving emails with invoices and statements. They’re saying my contract came back but how is it possible after 2 years? Now they say I owe them and but I didn’t reinstate the contract and I’m not even using the services I’m being charged for.

I’m not happy with Vodacom. Can you please remove the contract and amount on my name because I don’t know anything about it. And this is a mistake a Vodacom employee made and I have to pay for their mistake is not on at all. Please resolve this matter asap.
