Airtime and sms subscription being billed to my account without my consent

I previously wrote a complaint concerning a subscription I never agreed to. Now there's R176 that had been added to my statement which is really an inconvenience to myself. My premium has went up. I complained about this to avoid anything being charged to my account after I got a sms. The big question is why your people are calling us to offer something and say you don't have to subscribe to it then next thing you're being billed for it. I'm really mad at this and even considering closing off the account completely after paying it off. I'm seriously not happy about edcon. The reference I previously got is ********** **********
