Horrible service

I am writing this extremely frustrated with Vodacom and their service. I canceled my contract with them in November 2022, I then realised the debit order was still going off. Only to find out that the person who assisted me with a cancelation added a subscription on the number. I have never used this sim for anything else other than the data I had when my contract was still active. Now since December 2022 no one can assist me to cancel this subscription so that the debit order does not go off. The service had been horrible I will never take out any contract with. *** is inactive Vodacom is still charging me I have made multiple attempts to get this sorted but they are telling me to pay for a service I have never used
