That's indeed odd then. I'd suggest you get in touch with a member of the Spotify staff so that they can take a look behind the scenes for you 🙂 Simply, you can drop them a line on social media (Twitter or Facebook) or by using the contact form. Make sure, if you use the latter, to reply to the automated email you'll receive directing you back to the help pages, even if it's from a no-reply!
