Upgraded wrong account to premium

[sheth]

I seem to have two accounts: a spotify only and a facebook one, and have accidentally upgraded the wrong one to premium (spotify only).

My facebook account has all my music and playlists on. Is there any way this subscription can be transferred to my other account?

Have even asked @SpotifyCares on twitter but have recieved no reply

I believe that this solution should work. If that fails it seems that contacting Spotify Support would be your next option.
