First of all I didn't mean to change it.. so it was an accident and would like my username back the way it was.
Now let's go steps that I took.
-I Crated a new account to see those spotify premium sales and named it different than my own (ofcourse), but now MY OWN display name is the one that I chose for the second one.. which is a bummer because I liked my old one more :(
There is a picture where you can still see my old name in the top corner, but now it has changed also to the "new" one....
Is there anyway other than creating a new account change it back to my old one?
