How to access Spotify on new iphone

[mondaynight]

My old iphone has stopped working and I've got a new one (iphone 5). I've updated to the latest version of ios and Spotify. No updates pending. I've got a premium account. When I try to login on my new phone I get an error message 'Login failed - You've already created an account with this email address'. I'm not accidentally pressing 'create account', I'm pressing 'login'. 

Does anyone know how I can contact Spotify for support?
