Completely ridiculous.
Completely ridiculous.
I followed all of their steps for authentication, fulfill all of their requirements (old enough, German citizen, living in Finland) and they have the gall to reply with an email that states they "are not allowed" to say why they can not open my account.

Of course they are allowed to reply to the person who tried to open an account with a reason of what went wrong.
But they simply chose not to.
