Misadvertising bundles on the Vodapay App, terrible post purchase support

I used the Vodapay app to purchase a data bundle. I navigated to Data > 30 days and selected the following from the drop down menu (under 30 day data): 3GB + 3GBnight owl (14 days). When it loaded it said the entire bundle (3gb+3gb night owl) was only valid for 14 days. I phoned and said I purchased 3gb for 30 days and the app stated + 3gb night owl (14 days) - as the special. I stated i needed a 30 day bundle and requested a refund and cancle the bundle as it wasn't what i needed, or ordered under the 30 days bundle. They stated the entire bundle was 14 days. I sent them the screen shot showing the data bundle was under the 30 days and it is advertised as for 30 days you get 3gb and then you get 3gb night owl for 14days as the special on top of that. They refused to acknowledge that either it was false advertising or listed incorrectly under the 30 day bundles. They acknowledged all other listings in the 30 days were for 30 days but this one wasn't. It makes no sense. I then had to spend 1 hour on the phone with a very unhelpful call center agent and her manager who continuously interrupted me and made as I was wrong/stupid. After an hour on the phone arguing my point repetitively, they eventually refunded the bundle deal but said they only doing it as a gesture of "good will". This isn't good will, this is taking accountability for false advertising! If the 3gb+3gb night owl (14 days) is not a 30 day bundle then it should not be listed under the 30 day bundles. If it is only a 14 day for the whole bundle it should be listed under the 14 day bundles, not under they 30 day bundles, I asked for them to remove it and they said they can't. It took me over an hour to resolve this issue which could have been sorted in under 10 minutes if they had just acknowledged: 1)the advert on the app is at the very least misleading and at worst false advertising. When I show the advert to others they also said this is how they would read it. 2) The advert states 30 days bundle but is only for 14 days - then it should be and will be removed from the 30 day bundle options to avoid confusion for others. It's really not that confusing.
