Vodacom *****s!!

If you can change your network, i advise you CHANGE and FAST!!! Vodacom are *****s!!! Sterek!! I loaded R120 airtime, and automatically they change it to 1G data. I call them to rectify, they say they can coz i chose recurring. After escalation im told same. I insist, that i would NEVER choose 1G R80 data when i know for a fact i have the option of R12 1G per day, how stupid would i have to be to not know the maths to that?? Duh! I WANT MY REFUND. I didnt recharge my account for data, i recharged for a call! Why am i having data being forced down my throat at such an expensive rate???
