Vodacom - Dishonesty and misrepresentation

I recently (5/3/18) called the ********** line to cancel two of my lines and was offered an upgrade on my ********** 413 line. The consultant I spoke to when discussing the different options I had recommended the Red Classic package. When she told me that this package offers 4GB of data, I did not want the package as I need more date than 4GB. I informed her that I need at least 10GB of data. She then offered to give me 14GB of data on the package. Based on this I accepted the package. On the 7/3/18 I received a call to confirm my upgrade and the package. I informed the consultant that I was offered 14GB data on the package to which she rep**** that it is possibly only for three months. I specifically stated to her that my acceptance of the package was based on getting 14GB data as offered by Tshwarelo on 5/3/18 for the entire period of the contract and not just for three months. No one ever came back to me to say that this was not the case. On 1/5/18 I only received 4GB of data. I don't want this package and I very clearly stated this. Both consultants misrepresented the package to me to get me to sign it. This was dishonest just to get a deal. I would like my contract to be cancelled as this is not what I requested. I am escalating this matter to the ombudsman and will get legal advice.
