AirG Sunscription - Can't Unsubscribe

I have been trying to get rid of AirG Social Service - I did not subscribe to this, and I don't even know what it is. I've sent an e-mail to [Email Removed] but now they want a whole lot of information, I am not willing to supply and will only get back to me within 5 days, almost when the next R7 subscription is due I pay R7.00 per week for this service. Please help me stop this R7.00 per week.<br> Thank you
