I alredy read "Can I recover a deleted message in Hangouts?" and saw the solutions in reply section which is Amelius answered in Dec 21, 2015.
But I can't find my chats on Gmail chats folder. It's already deleted a few days ago(and i deleted it for good). And the other party also deleted the chats. And I didn't archived the chats....
Then... is it impossible to recover the hangout chats ?
And I wonder that are there any phone number of hangout help center(?) ? I really want to counsel about this thing ...
Thank you for reading this !
Hope you have a good day ;)
