stolen account

[19DREW91]

More than a week ago i couldn't log in to my spotify account, and i couldn't understand why. A few days ago i found a mail in the spam from spotify authorizing a mail-change not asked by me. Yesterday i finally menaged to log in trough my facebook account. I changend my password and upgraded my security set-up. Now i have two issues: all my playlists are disappeared, and i couldnt even restore them. And i'm no longer premium. So i ask what can i do and how is the situation of my account. Thank you very much.
