*****ing money from my account

For over 5 months, Vodacom was charging me for something called \content services". I phoned them thrice before they eventually cancelled it and stopped charging me the R7 per day. Vodacom claims to have no involvement as it is a third party but the money is paid over to Vodacom every month. How does this even make sense? I was told to contact the company Backbone myself for the refund but they are completely useless and Vodacom does not get involved at all. Can you please explain how this is allowed and when my account will be refunded. """
