Vodacom AirG spam smses and ******** billing

Like MANY other Vodacom subscribers have complained, I also receive many smses from vodacom with the following: Your recurring R7.00 Subscription to AirG Social Service will be billed on 2015-04-21. To unsubscribe click [URL Removed] I did not subscribe for this so I want to be unsubscribed IMMEDIATELY!This is absolutely ridiculous and completely against what one signs up for.<br> <br> PLEASE remove this completely and immediately, as well as any other spam messages that get for other services that I never signed up for.
