fighting for refund after costs taken without my knowledge and NO assistance

I have been fighting now for 3 months to get a refund, and im still fighting for money to be paid back, vodacom says its not on their side but they are my service provider and they charging me. To date im waiting for proof of me accepting data services or agreeing to anything online. why is this such a uphill with no assisttance...?

been told to handle with the supplier/complaints, do this and still nothing happens, another month goes by and im still no where??
