Go to the point where you want to go and ,if necesarry, also describe your problem!
If you get a non-reply Email, just reply and will be connected directlyto the Support. And what do you actually mean when you say: "i don't even know what is spotify."? Because if you get an Email like that, a Spotify Account is requierd. Did you maybe forget that you've created one or did you give your account details to another person?
If you have any further questions come back at me!
