**** confirmation of cancellation

I have been trying to cancel my dad's Vodacom data contract from June 2023 - after we both spoke to the call centre to dispute the contract renewal 2 years ago, it was finally confirmed telephonically that the contract is now cancelled. On the Invoice dated 1 November 2023 the deduction for the data contract again went off his account. Please can someone with proper knowledge and client care e-mail my dad with cancellation confirmation, STOP the debit order and refund the deductions which were taken. We also requested the telephone recording where the contract was renewed, but nobody seems to be able to help with this.
