Robert Hi!
First of all, if you created an account you indeed have to be verified. After you sent a picture of your ID card, recorded a video, and sent additional documents, bunq has to verify your account manually. This takes anywhere between 5 days and 2 weeks. In the meantime, your account stays in the demo version. Be patient! You'll receive a notification when your account is verified.
Bunq support isn't available by phone, you contact them via the in-app support chat. Bunq will never call you. Bunq support often replies within a few hours, but sometimes - when it's busy - it can take a few days.
