AirG Social Service

I am so tired of being used by these Big corporations, who think they can get away with things like this. I got a message a while ago saying My AirG subscription will be billed on 2015-04-18 on my phone, so went to the link they gave me and it took me to a blank Vodafone page... So I shrugged it off after I tried unsubscribing from all services using various Vodacom methods and to my surprise I was told I wasn't subscribed to any services. I then started noticing a week later airtime was going missing even while i wasn't using my phone, called Vodacom when I was sure something was wrong and they said I should click on the link. I am very disappointed that this could happen< my issue is still yet to be fixed and now airtime has been going missing since I got this phone and on top of all these things, I am a student and the money I barely have is being taken away from me from something I don't even know the functionality of. I just want someone to answer for this and I want to be reimbursed for the money taken from me I didn't even know about.
