Useless Data contract

I received a call if I wanted to change the data on my uChoose Flexi plan from a topup to a 24 month datacontract (2GB MBB 24 Month) and still use my existing number.<br> I agreed to this and it was send to me on the 13th of October. I did not need the data until November, and I left the sim card on the shelf for a few weeks.<br> <br> When I tried to use it, I noticed that I could NOT use the data from the data contract on my phone. I called and was told to go into the shop to have the sim cards linked. Went to the the shop and was told that the two sim cards can not be linked and that I must walk around with a mobile wifi gadget to use the data! <br> She told me to phone vodacom aftersales to sort it out. vodacom aftersales told me to phone cancellations.<br> I'm sure that cancellations will tell me that I can not cancel because the cool of period has expired.<br> <br> Is there any way that this contract can be cancelled, or if the data can get transferred to my uChoose Flexi 150 plan.<br>
