Geoffrey Hmm... 0 cards just sounds like you don't have any active cards. Why that is the case is hard to say without having access to your account or knowing what exactly you have done. But just to reiterate on one point that's very important: the IBAN that is printed on the back of the Maestro cards at bunq does not have any significance. It does not mean that the card is actually connected to a sub-account with that IBAN, it is just one IBAN of one of your sub-accounts that you chose when you originally ordered it.
Bernd already asked you what type of membership/plan you have. "Maestro" or "normal one" is not the name of a plan. At bunq the following plans exist, and you can choose freely between them depending on your individual needs:
- Easy Travel (no monthly fee)
- Easy Money (7,99 Euros / month)
- Easy Green (16,99 Euros / month)
You can look up which one you're currently using by going to the Profile tab > Settings (top right) > My plan. The different plans have different capabilities. So for example on the Easy Travel plan, you can only get one type of card, the Mastercard Credit aka Travel Card. If you have any Maestro cards, you need at least the Easy Money plan to use them. Also the Easy Travel plan restricts you to having a single sub-account (technically not even a full bank account, as you only get that with Easy Money), so you not being able to create or access multiple sub-accounts might also stem from you not having the right plan. That could be one thing you might wanna check out.
Otherwise if you cannot figure out things on your own the right way would be to contact Private Support again and ask them about it. They have access to your account and can for example tell you why you see a 0 at the Cards tile and if you have blocked any cards in the past, maybe even by accident. If you still have any general questions, of course feel free to ask :)
