All my playlists are gone

[Wolky]

I just logged into my account and all my playlists were gone. And in their place was some weird random playlist I have never seen before and nothing else. 

Hence I logged out and in again but nothing changed. 

Then went onto the website and tried to restore most of the playlists, but only about half showed up in the restore deleted playlists column and despite constant refreshing, the other ones are still missing and i am at a loss how to get them back. 

Any clues?
