Frontaal Film Hi 👋
I'm not a 100% certain on this one, so best to check with bunq via the Support Chat 💬
But int the terms and conditions the following is stated about the cancelation fee:
If you decide to cancel the switch service during the thirteen (13) months period after the switch service has become active (after acceptance of your request by us and your old bank), we will charge you €129.63. These costs may change over time. We will charge the actual costs.
So to me it seems there are no costs when you cancel before it's activated.
Have a nice day! 🌈👍
