Ruud yes, unfortunately due to data leaks scammers these days have your personal details.
What I would do in your case (and what I did in my case), is add a new IBAN to your bunq account. Connect all your cards to the new IBAN. If you get a salary, ask your work to start transferring it to the new IBAN.
Then every time you see activity on the old account, like some subscription - change it to the new account. In time there will be no activity on the old account anymore, empty it and close it.
Next time they call and give you the details of the old account, you will know immediately that it's a scam.
It's a hassle, but it's worth it for your peace of mind.
