Deleted folders - not visible in BIN

Hi blazjemec, 

Welcome to the Box Community, I'm happy to help!

If the deleted items are no longer in your Box Trash, there is still a 14-day grace period for paying customers, during which Product Support can recover your content.

Upon checking it looks like this issue has been resolved in your conversation with one of our supported representatives who helped recover your folders.

You can check out our article on Managing Trash to learn more about Box policy on recovering deleted items: https://support.box.com/hc/en-us/articles/360044196093-Managing-Trash

Thanks for posting and let us know how else we can help!

Regards,
