Several days ago when I entered my account is listening to music from Spotify Web Player. When I see it the first time I change my Facebook password. But my Spotify account can be entered from my email and a password that I do not know when I put it. The fact is that someone uses my account and the password of Spotify can not change it because every time I give "I forgot my password" it tells me that my account is created from Facebook. Right now I do not know how to solve the problem and I'm worried.
