Service non existent

People let me warn you about Vodacom, I had a contract with them, I thought it would automatically stop. It did not, they billed me almost blacklisted me. Told me I have to pay till Oct 2022 than the contract will end. Again same thing than end of December they send me another bill, I called them and did the cancelling again. Which I spoke to a team leader who helped me. This month I got another bill from them after telephonically cancelling my contract. My credit score keeps going down due to this, they are playing with peoples lively hoods. When taking out a contract please be careful.
