I rented a Tesla Model 3 for a week on vacation last year, and had linked my Spotify account without signing out. Ever since then, other renters periodically try to use my Spotify account (which is still linked to the Tesla). I've tried the following without success:

• Signout everywhere (doesn't seem to work since it's a partner device?) 
• Changed my password 
• "Forget device" whenever my music streaming switches to the Tesla - but it keeps coming back  
• I've looked through the Tesla Model 3 manufacturing guide, and it doesn't mention how to UNLINK an account, just how to set it up
• I'm also not in contact with the original owner of the car

How can I remotely get this Tesla to stop having access to my Spotify account? Thanks!
