Im sorry for you OP I know how horrible it can be to think you made your character they way you want and when in the world everything's off and it's disappointing(or hitting accept before done). Especially when you have worked on this character. Though I agree with the other posters that it isn't really SE's fault and you shouldn't throw the "im quitting" card, SE has indeed mentioned about a beauty shop of sorts. So if you can live with your mistake a while longer, eventually you will have the ability to change your appearance. If this is too long, perhaps count your losses and try a new character. I would suggest making a alt and putting them in the world with saved to server slot so once you have them the way you like you can just pull up saved data and name yourself.
