vodacom practices false and misleading advertising

Once more vodacom is misleading its clients. Where do I begin? I purchased R100 airtime last week and converted R59 to a 250 mb data bundle.. what happened to that data bundle even though I barely use my fone and didn't download a thing? Only vodacom knows! Then I receive an sms encouraging me to download the app and recieve 1G data.. think that actually materialises? Think again! Next I receve notification that should I use said app to purchase data, my data would be doubled over a seven day period.. take a guess! Of course! BS!
