Vodacom Poor Service

I contacted Vodacom in January 2024 to cancel my contract. I planned on giving one months notice. I was told that since my contract had expired, I didn't need to give a month's notice. I asked for it to be converted to a prepaid number.. Fast forward to April. After numerous calls and promises that all was in order and my contract had been canceled, I was still being debited. Finally, someone told me that even though I had spoken to 4 different people, not a single one of them had done their job properly and actually processed the cancelation. By this time I had reversed a debit order because I was sick to death of my requests being ignored. She said that it would be investigated and I would probably not have to pay anything because it was supposed to have been canceled in Feb. The next day my account was on prepaid and without any notification they debited double from my account. I sent an email explaining my situation and told them that since no one seemed to be taking me seriously I was reversing the debit until.someone came back to me about my escalation and the outcome. Today the 25th May I get a message threatening to hand me over. I have never received a call from.anyonre and it has been 25 days after the mail. I went in to the store today to ask for advise and found out it had been listed as an early cancelation. I have been a customer for 24 years. I am disgusted by the quality of service and will never recommend them to anyone. At the moment I just want to pay them so that I never have to deal with them again.
