I didn't subscribe to AIRG Social service

Like another Vodacom subscriber complained, I also just received a sms from vodacom as follows: Your recurring R7.00 Subscription to AirG Social Service will be billed on 2015-04-18. To unsubscribe click [URL Removed] I did not subscribe for this so I sent STOP ALL & STOP ALL WC. And I want to be unsubscribed IMMEDIATELY when I click on the link it only takes you to vodacom site! <br> <br> Coincidentally I received another on the 2015/04.09 and Really though it would stop since I sent sms's to 30333 to unsubscribe all WASP services. <br> <br> It replies that I am not subscribed to any WASP service so what give's. Why am I getting these Sms I didn't subscribe to any weekly waste of money and why does your 30333 number not remove the WASP if there is one!!!!
