Hi everyone, and welcome to the community!
I suggest you both submit an online contact form; and someone at Spotify should be able to get rid of the facebook connection (if it is still there) and restore everything for you.
If you get an automated reply; make sure to reply to it directly (even if it's from a no reply); and it will be sent to the Spotify staff.
Also, make sure you log in with your username not fb email once it is done, as if your account is disconnected from fb the email won't work anymore.
