Chargin account every month without my permission!

I just looked at my Vodacom itemised billing and I have been charged numerous times every month for GAME CLUB?! R4.38 per charge. I called Vodacom now to query this as I did not enable this and do not even know what Game Club is. I want this money refunded to me they are *****ing money from customers without their permission. The lady told me you have to go onto the Vodacom website to do this...these charges are occurring repeatedly at 5:30am in the morning and I am asleep at this time not on their website! These charges are **********! I don't download games at all! I want this Games Club removed from my profile and all charges related to this refunded to me! Watch out for this on all your bills as these are occurring every month!!!
