Vodacom Insurance

I have been dealing with the same issue for 4 months now. Firstly, you are put on hold for over 10 minutes when you call the call centre on ********** regardless of the time of day you call. I cancelled my device insurance in November 2018. I am still being billed for device insurance every single month. I have called numerous times regarding this issue and it STILL has not bein resolved nor have I have been refunded. Every time I call the call centre, someone promises to call me back and they never do. A new query is opened every time I call with no resolution. The service I have received with this query is appalling.
