Hi, as I tried to listen to music with spotify some days ago I found out that my account wasn't premium anymore... I don't understand how it's possible, I won a contest and got a year of spotfy premium free (it should and on March 22. 2018... I have the receipt and everything you want to prove it's true but now when I go to my account it says I'm a free user... I'm very confused please help me! Thank you very much
