Vodacom Insurance Nightmare

Horrible service. Cancelling device insurance has been ongoing for 4 months now. I called Customer Care to cancel my device insurance on the 29th of November 2018. I am STILL paying for over R170 per month for a service that I cancelled. I called Customer care for the 5th time this year and it is STILL being escalated with no resolution. Now I am being told that I must hunt down the insurance provider myself and cancel it myself. I was told that I have to pay the full invoice amount every month including the insurance or my line will be blocked.
