AirG Social Service

I receive messages from the above mentioned service - I have never subscribed to this and they bill me every week. It gives you the option to unsubscribe but it is impossible to work this unsubscription out. I do not want to be a member and I want to be refunded. It even asks for my user name - I am not even a user and have no idea what this is. I notice a lot of people complaining - does Vodacom want us to each complain individually!!?? How about just unsubscribe everybody who did not subscribe in the first place?<br> <br>
