Peter Joseph Hi! You can easily change your plan: http://together.bunq.com/d/3317
You started at bunq with a free 30 days Easy Green trial. But since you didn't change your plan within those 30 days, you started paying for this subscription after the trial was over.
If you're not familiar with the bunq subscriptions, I highly recommend you to take a look at bunq's website and compare the plans: https://bunq.com/benefits/
