Fuming with anger

I'm fuming right now this battle with vodacom is exhausting. After they reverted me to my old contract of 50G for R249 I just received my invoice stating I'll be paying R365 I don't understand where that amount comes from. They call me this week telling me that my contract has been canceled and they even told here on helo Peter after I reported them to the NCC. I swear if vodacom charges me again in September I'm taking legal action. We should all have a class action law suit against Vodacom for breach of contract.
