Vodacom incorrect billing for content services charges

My September invoice shows charges for content services of R190.98. When I queried this with Vodacom customer service, they say it relates to WASPA for subscription services. I have never subscribed to any content services and yet I am being billed for it. Vodacom says they can't do anything and I should follow up with WASPA. I have been a Vodacom customer for over 20 years and am considering leaving, as no one at Vodacom can assist. They blame WASPA every time I phone and follow up. If WASPA is the problem, why is Vodacom billing me incorrectly and why should I follow up with WASPA? Also this month I got 2 sms stating i have been subscribed to 2 other services which i did not request. The customer service centre is clueless on how to resolve this incorrect billing.
