All my playlists and premium subscription switched to a different account?

[user-removed]

As the title says, all of my playlists and premium subscription switched over to my friend's account, erasing her playlists in the process.

The only thing I think could have caused something like this was signing onto spotify on her iphone.

Help!

Help? It's been like this for a month now, and the support team still hasn't helped me.

Same problem over here, found a solution yet?
