Vodacom debiting my money without my permission

I had a contract with Vodacom and it came to an end, they did not want to end the contract tgey kept on debiting money from my account. I then wrote here on Hellopeter they reversed my money and agreed to close that contract and that was 2022. Today in 2026 they debited R473.29 without my permission, it declined because of insufficient funds and they telling me it's an outstanding balance from that contract which was terminated on 2022 they want to **** me
