Shocking service from Vodacom

For the past six weeks I have been trying to get Vodacom to reverse an amount of R265.00 which they charged me in April 2021 for insurance on my handset which I did not request. To date despite numerous calls to their various departments and assurances that they would 'escalate' the amount is still owing and I receive daily automated calls asking for payment if I still wish to remain connected. The revenue number I include below was given to me by CustomerServices on 8th June 2021 with a promise of 24 hours for assistance..still waiting. This is shocking service to say the least.
