Only the common points of confusion
Choosing a plan alone does not change your subscription. Changing from a single-service plan to Bundle may create an additional charge at the time of change. Changing from Bundle to a single-service plan does not refund the remaining period, and switching between single-service plans does not adjust the price difference.
If cancellation is already scheduled, changing plans cancels that schedule and continues the subscription on the new plan.
Opening Stripe billing management alone does not update payment or billing information or cancel your subscription.
After cancellation, BananaNL remains available until the end of the current billing period. For refunds and plan-change handling, please check the Commerce disclosure.
However, if a core feature did not work right after purchase, or if you can share specific details about a bug or usability issue, we will review it individually. Please contact us through the support form or email with your environment, the screen where you had trouble, and what you expected to happen.
