Deals listed on the app is not accurate!

Products advertised wrong, after choosing the product on the app and doing an online upgrade, I was told afterwards that the actual deal that you get is not is not as shown on the app that I chose. I managed to cancel the upgrade by calling Ram couriers twice and Vodacom 3 times. All uchoose flexi plans shows voice minutes on the app and not airtime. The plan I wanted states on the app: uchoose flexi 390 with 390 voice minutes for R299 per month. But then they told me it’s airtime not minutes. Then I had to cancel the upgrade.
