*****ing money by adding own charges onto account

Vodacom somewhere along the line registered my for some vlive game in March. Unfortunately I did not pick it up straight away as I buy data every month and assumed the higher charge was data. I picked it up this month and i am being charge R4.95 a day for some game i have never registered for. Vodacom refuse to take this months charge off my bill. So in essence they have been *****ing from me since March, i have not even tried to fight for the money they have already ****** from me, i just want them to stop *****ing from me and they won't stop. The thing that ****es me off even more is to deregister for this game thing you have to confirm that you want to deregister but they register you without confirming or contacting you, it's an easy way to ***** their customers that are too stupid to check their invoices correctly of which i was one unfortunately.
