Unable to purchase data via App

I have been trying for the last 2 weeks to buy data via the Vodacom app. <br> First it gave me some ridiculous message about not owning my number. <br> Then the app would just shut down.<br> New update yesterday morning: now I can get to the end of the purchase and it says it was successful but i am not getting the data (did this twice).<br> I even tried buying data via *111#... and it said Vodacom will verify and get back to me... nothing.<br> <br> My phone is a Samsung S6.<br> <br> What does one need to do to buy a data bundle on a contract. This is unacceptable. This used to work fine but the last 2 app updates have really messed it up.<br> Please fix your app!<br> <br> In the meantime, i am forced to use out of bundle rates and I am starting to wonder if this is your way of making money!<br> <br> Really frustrated and considering changing service providers in the near future!!!
