Misleading/inaccurate information

I get an email about all the benefits you can get if you apply for a Discovery card, which I then do. Also note that with recent updates, you cannot use Vitality travel without a Discovery account anyway. They don't want to give me a credit card, which is fine, I already have one. So I open a current account. When my card and the app is up and running, I get messages in my app inbox welcoming me and telling me what if I spend money in the next 60 days I can earn Discovery Miles. Next message comes along, saying that if I spend a certain amount with my virtual card, I can also earn Discovery Miles. So I do all these things, time ticks by, and no Discovery Miles. I then send two emails to Discovery Bank complaints, one on 6 April and then again 19 April. No response. Eventually I phone the bank, and am then told that 'it only counts if you have a credit card account or full suite'. Now please note, NOWHERE in these app messages does it state that these miles can only be earned by 'credit card or full suite holders' (I have screenshots). This leaves a few questions: 1) Why do I get these messages on my app if it only counts for credit card accounts and I do not have one? 2) Why is it not made clear in these app messages this only counts for specific accounts? 3) Why does the complaints department just ignore me? Honestly, it feels like inaccurate and misleading information to get people to spend the money or do whatever it is they want you to do, just to add this little caveat at the end that was not specified! The telephonic consultant has now logged another complaint on my behalf, we will see if anyone even bothers to respond to it.
