A part made to your file and parameters is a custom-made item. That is why there is no right to withdraw from a distance contract (Art. 38(1)(3) of the Polish Consumer Rights Act), also for private persons. You confirm this when ordering.
What you can do instead
- cancel the order at no cost before payment (Cancelling an order),
- file a claim if the parts do not match the order (How to file a claim),
- cancel at no cost when shipping is 3 or more business days late (Lead time and delays).
