On line Upgrade Nightmare

I upgraded my contract in September and was told the consultant explained to me that i will pay 189 for the 2gig and 220 airtime and the device, but he also explained to me that because the previous contact had not ended i will also continue to pay for the old device until the old contract ends which brings the total to 209. On the 1st of October i did not receive the airtime not the data and i called the call center and spoke to Rebecca who assisted me and said they loaded the airtime on the 30th and it was taken by internet usage and the date she loaded that time, asked her to ensure that the sms for my number come to my number which she didnt do, she said according to her my new contract is 489 which is where the problem started then she said she will check again and call me cos that;s not the amount i agreed to, she said she will call me and today i called back as she didnt call me back.

Today when i called im getting a shock to hear that i didn't pay last month...what i asked the consultant was if i didn't pay do you think Vodacomn was gonna leave me alone. All i want to know is how much the new contact is and what i will be getting as everyone seems to have a different story.
