contract data

I have a problem with Vodacom network, four months ago the consultant from Vodacom contacted me to sell the DATA (20gig during the day and 20gig night) which he said will be free for the first month, I was surprised when R210 was deducted from my account the same month, I could not understand why the R210 was deducted after the consultant said it will be free in the first month, otherwise I would not have taken the product. And on top of that, I was given 10gig for the day and 10gig for the nigh. I came to conclusion that the consultant miss-sell the product to me in order to benefit his productivity, then I decided not to honour the payment onwards due to mis-presentation of the information from this consultant. I am very angry now because my cell phone number has been suspended, and I can not perform any activity in cellphone banking since I have registered the same number. Today I was supposed to make a transaction in my cellphone banking, but I could not do anything due to this suspension. I have have R30 airtime on my simcard of Vodacom, but I can not use it at all. I think something need to be done here. The call recording of this consultant need to be investigated. I contacted Vodacom several times present my case and nothing has been done up until today.
