Double data promise?

<p>I have been unable to purchase data using your app for 2 months now. I called the call Centre and they loaded data manually then also said they will send an escalation to have the double data credited to me since your app didn't work. I never received any call, but only a SMS saying we can see you have purchased data please call if you need help. This month again I am unable to purchase data, I called and after so many different stories someone manually purchased data , however I am still unable to purchase for myself using my card on my banking app, your useless app or the vodacom site. I want 10GB of data owed to me as your app didn't work when my intention was to get data via that channel and what ever I still owe on this contract to be written off due to incorrect information provided and blatant inconvenience then please cancel this contract so I can move over to cell c. </p>
