Cancelation Complaint

I have been trying to cancel a contract with Vodacom since March 2020. My reference number is ***. The call center *** has been ignoring my requests. I have spoken to more than 5 people who promise to help me but I get no where. All the consultants have promised to get this sorted out and revert back to me, however to this day, no one is willing to assist, when I ask to speak to a supervisor, they refuse, some have kept me on hold for over 20min and eventually cut the calls, some have transferred me to the call rating while still speaking to them. What kind of service is this? I would like to get a refund since Vodacom keeps debitting an amount from my bank account, and to get a superior to contact me and sort this out, I shall be posting this complaint on every platform available, social media and ombudsman if this query is not attended to.
