Content services ********** charged to my account

I approached Vodacom about a content charge appearing on my November Stmt. The customer service agent at Vodaworld advised me that Vodacom is not responsible but third parties which work with Vodacom. She then advised me that Vodacom will not refund me the money as the did not initiate the content charge. She also advise that ICASA was aware of these ****s. What I found disappointing is that invoiced charge is on the Vodacom stmt and invoice. The money deducted from my account went to the Vodacom account. I do not understand how ICASA has allowed Vodacom to do this to us . Vodacom is committing ***** and this needs to called out
