Vodacom Cellsure worst service ever. 4 years of issues

Vodacom and Cellsure(compsell) has been delivering far below horrible service. Takes them 9 months to sort out claims. They make mistakes and refuse to fix them although on recorded phone calls they state they see a consultant made a typing error but it will still cost me money. Last month i had one device insured, this month..... My invoice has 3 premiums for insurance i did not ask not request nor authorize. When you get a hold of the insurance company the consultants are useless to say the least, can never give answers/proper feedback. Requesting call back.... Ghmmf. Never call back. This is by far the worst company i have dealt with on insurance. I have been a client at vodacom since 2006. I am at the point of cancelling all 5 my contracts with Vodacom due to their insurance underwritters.
