I have a box account that was set up by a third party company in order to share documents.  The contract with that third party company has ended, but the documents provided and created where my companies, but they are no longer showing up in box.  I did not receive notice that my account was being deactivated or the documents in box would no longer be supported on the platform.  I do not know the reason for the documents no longer showing up, but is there some way of retrieving possibly deleted documents?

Thank you.
