Thanks for reaching out to the community! Many other users have been encountering this problem as well. As far as I know, Spotify have done this to accounts they felt were unsecure, other community rising stars/rock stars here are more clued in than myself about this. Anyhow, you should reach out to Spotify customer support and let them know about this, they'll be more than happy to help. Hopefully it shouldn't take too long to get resolved.
