Billing Their Clients for subscription that was not subscribed for

For a couple of months now Vodacom has been billing me for a Content Services, up until recently i only noticed the amounts on my details statement. I questioned it and Vodacom indicated that Vodacom has been billed for something i subscribed for on the internet, a "Waspa" account. I never subscribed to this and it is clearly *****. When i queried it the lady who was in the customer service department immediately unsubscribed my Waspa account. She gave me a number to phone and told me i must sort it out with Waspa, Waspa says that i never had a subscription with them and denies paying my money back. How can Vodacom just assume that i subscribed and that they just pay on my behalf, this is my hard working money that they just loosely giving away. This is why i have cancelled my contract with Vodacom and will NEVER ever get another contract with Vodacom. A couple of years ago i had a similaur situation but with Vodacom charging me for cell insurance, and i know for a fact i said no to cell insurance. When i queried it they said they once again assumed i wanted insurance on my cell phone. Vodacom *****s your money, why sign up for a contract and having to make 100% sure each month that they are not taking extra money for their own pockets. Billing their clients for stuff they never signed up for, *****!!!!!!! I will never ever recommend Vodacom to anyone.
