Mis informed/ Incorrect information supp****

At the beginning of last year then I had an upgrade to the Z10. The retention consultant misinformed me I agreed to the upgrade and have been trying to have this issue resolved since last year already. I asked him to give me another contract similar to what I had ( /- R300 per month ). Kevin from Autopage informed me that he can give me another phone for /- r80 more. I agreed and then received my phone. When I received my first bill I was however shocked to see that my phone bill increased from =/- R300 to R1738. I called Kevin and he informed me that I pay for BIS and that I should not be charged for accessing the internet. When he reconfirmed this then he changed his story and told me I have a phone with the newer Operating system which means that I will need to buy data. I then reminded him when I agreed to have a agreed to the upgrade. He informed me that he will escalate me problem. I am struggling until now to get any feedback. PLEASE HELP!!<br> I called Kevin manager Nomvula and also sent her a few e-mails to which she never rep****. I called Autopage head office numerously and the Standard reply is that they will escalate the issue. I never once received any feedback.
