VODACOM ARE THEIVES! REFUSE TO CANCEL CONTRACTS AND ***** MONEY!

I have been phoning the call centre requesting a cancellation of a 4 year old contract since August 2020. By their own admission, Vodacom has confirmed that the agent in question did not action the request. I have been phoning the call centre since then - 10 months, requesting a refund for the 6 months of debit orders that were deducted from my account, dispite my cancellation request. Every time I phone they suddenly cant find the action request and the whole process starts all over again. In march 2021 an agent actually changed the commencement date of my "contract" so that I cant cancel it. I am now fed up and tired of being patient. I've been asking to speak to line managers and supervisors and I've been fobbed off at every request. Last week I was assured that the line manager had listened to all the calls I've made to the call centre, and that I am correct in that I made this request last year August and it wasnt actioned, and that she has escalated an instruction for refund of over R3500, and that I would receive an email and sms from vodacom confirming this within 48 hours. The consultant said she would personally follow up with me in 3 days. It's now been 7 days with zero confirmation, zero follow up and I'm currently on the phone with the call centre as I type this being told there is no record of my comms and a line manager who refuses to speak to me. This call is currently sitting at 35mins and counting....
