you say you used your friend ps3 because you didn't have a copy of the game yet? did you used your friends square enix account to log in an create a character to play? if so that character is tied to the square enix account in which it was created (which would have been your friends since you didn't have a copy of the game yet), doesn't matter what psn account was logged in at the time. So that might be the reason the character isn't showing up in your account now that you have the game.
