Double your data not allocated

So I use the Vodacom App to purchase a data bundle, 250mbx2 for R59.00. I only receive 250mb. This is not on. I phone on Tuesday evening and the agent promise to phone me back. Nothing. I phone yesterday and the problem will be solved in 7 days. 7 days?? Am I suppose to buy more now, with my money which has now been ****** by Vodacom? I phone again today and now I'm told I did not use the app. ***? I am so cancelling this contract. Ref 1-3 ********** 120
