VODACOM GET THE QUALIFIED CONSULTANT

I'm not happy with Vodacom last year we had agreement for iPad contract and I was told it will be R80.00 per month. November my first payment was + or - R250.00 then I reversed amount with my bank as it was not our agreement second month it was R300.00 + then I called asking them why so much and I was told it was connection fee. But I refuse to that as it was not disclosed to me when I took the contract. Everyday when I call Vodacom they tell me I cannot cancel contract and I must pay now R569.00 or they are going to list me on ITC but I think it is unfair for me as customer to be treated like that. my account for Vodacom : I ********** -2
