Recover deleted drive document not in trash from url

[Luc_Daan]

Hi everyone,

A document of our Drive as been deleted for no apparent reason, I still have his URL but it shows me an error.

https://docs.google.com/document/d/164sYLflTXvgtT0vTgpcb_RE3PR3KZlvy0NAMNWv_6nU/edit

I can't find any information on the deletion date or and the document is not present in the trash.

His there any solution to restore this document or to get access to a Google Support for this ?

Thanks for your help
