waste of money, energy and time

So yesterday on 12/04/2016 after purchasing airtime i receive an add saying get double the amount of data you buy if you use the vodacom app which is 20megs to download, so i buy airtime so i can buy data only to download this app so i can buy the data i want, after downloading the app i see a message saying my data will not be used to access the app because its free. I had difficulty accesing the app without data and ended up buying more data via *111#, again i tried buying data via the vodacom app but keeps giving an error saying 'you have exceeded the amount of data or airtime you may purchase', i did not even use this app once, the only use this app has is to devour my bandwidth! Now vodacom i want my all my airtime/data back which i have used on 12/04/2016 because i have wasted my time, energy and money thinking what was advertised is some how real and true(false advertising), or another **** trying to get us to utilise large amounts of data at once. Vodacom data is already expensive and still you're to rip us off, NO!
