Vodacom - Contract Cancellation still not done

Morning, i had cancelled a contract on the 24th August 2018 (premature cancellation). Payment, id and quote all emailed to the cancellations department. Called on Tuesday the 28th and was advised it was still not cancelled and was escalated to a manger and would be done in 24 hours. On Thursday i requested again and received the same reply. Now i have a contract that was cancelled but will be billed this month for it when it is not in use until Vodacom decides to cancel my contract. I have 4 contracts with them and am appauled by this level of pathetic service. i would appreciate if someone from vodacom contact me and cancel my contract immediatly and reverse any charges for this month.
