Liviu Vasile Hi! You started with a free 30 days Easy Bank trial. Because you didn't change your plan within those 30 days, you now started paying for this plan. You can easily change your plan in the bunq settings (Profile > Settings > My plan).
If you want to compare the available plans, check bunq.com.
You should've received multiple emails and/or in-app notifications about this, and it was also indicated at the start of your trial.
