Hackers?

I got an email from spotify earlier this week (around march 7th) saying that the email for my account had been changed. I didnt change my email, so I tried to open the spotify app on my phone to see what was happening, but it was logged out and when I tried to use my password, it didnt work. I tried on my computer, but the same things happened. so I called my friend and asked if I could use her spotify account to check on my own, and all my public playlists were deleted, my profile picture was changed, and all the artists I followed had been cleared. what should I do?
