Pathetic Service from Vodacom Insurance

It is my second time complaining about vodacom insurance that i have a policy that they should cancel. If i phone the line gets dropped. I get contacted by insurance company and they confirm i haven't got a active policy by it still reflects on my account and gets debited from my bank account. It is going into the 3rd month that i am paying for something i do not want and want it to be canceled. Will i be refunded for this inconvenience of Vodacom Insurance Company for their negligence and unhelpful customer service.
