BeFit Subscription Services on mobile router @ R7.00/day - THANKS VODACOM

So in the last few days I have received SMS notifications on several of my Vodacom contracts to confirm my subscription to BeFit @ R7.00 per day. While on mobile devices I know that this can accidentally happen resulting in ridiculous daily charges, I have now received the same sms on my wifi router, the cell number for which has never EVER been used for anything other than internet in the router. There is no way anyone accidentally subscribed to a ridiculous service and there is also no way that any other entity besides Vodacom has this mobile number and is aware that it is in use. This basically confirms that VODACOM is responsible for us being subscribed to these services.
