Vodacom and Finrite are the worst in the world

I have been trying to cancel my insurance with Vodacom since April to no avail. When you take cover, it gets activated immediately but when trying to cancel its a mission. I will be charged this month for a service that I have canceled. Whenever I call them and get transferred to the insurance department, no one answers. if you on hold for 30min+ your call gets dropped. When the agent connects with them, they come back to me to confirm that it is canceled but its a lie. They keep canceling accidental damage, which I canceled in January 3 2019 to take comprehensive. Now I have been trying to cancel comprehensive since 1 April 2019 to no avail. This works for them cause they keep charging me R305 every month. I will be charged this month for a service I did not request. Never insure your device with Vodacom, finrite (company handling Vodacom insurance) is the most useless company in the world. I cannot be charged this month. Please fix this. I do not want your insurance.
