Almost lost my data bundle

I am currently on a pay as you go deal. I went to a vodacom to get a new phone deal. I was about to sign up for a 2 year contract valued to over R600 per month going vodacom's way. I still had about 1.7 gig of data on my current pay as you go. I asked the consultant if I'm going to keep this data. He said no. I then shoved the contract I was about to sign across the desk and told him I was not interested anymore as I did NOT want to lose the data I paid for with my HARD EARNED MONEY! And to think i was about to sign a 2 year contract and in the process give vodacom a lot of money but they can't even let me keep my data.<br> Come on vodacom!! I did not ask for free data. I ONLY asked to keep the data that I've already paid for!!<br> I tell you what. If I can keep my data I will take out a contract this week!
