Insurance *****

Ive called vodacom 4 times to cancel my cellphone insurance ( since february) and the insurance is still not cancelled. The last three times I was told that the matter is escalated but they still havent cancelled. After holding for almost an hour without assistance , I was given the email of the supervisor who also hasnt rep**** to the email i sent. They have debited my account even after numerous requests for cancellation and have made it extremely difficult to remove this product from my insurance.
