Cancelled contract by e-mail, but I get billed continuously.Why?? - Consumer Complaint for Vodacom - Head Office

I have sent 3 separate cancel my contract requests during July,2020 with no feed back from Vodacom. All I get is my bill which you forcefully apply via a debit order. In each case I have got the bank to reverse the debits. Contract cell number 0769213403. e-mail addresses used as per web page cancel***@vodacom.co.za & also retentions.cancel***@vodacom.co.za
