Fantasia potion gave me the wrong character?

I tried making a miqote character using a fantasia potion but it ended up giving me a lala? is there anyone that can help me out with this? or even just give me back the potion? its kinda hard playing like this.

Did you have the lala saved, like from making a retainer or something? Maybe you selected the wrong saved character slot in character creation and didn't notice until you logged into the game. I don't think they'll give you a refund on the fantasia, you could contact customer service and see how far that gets you. Maybe just pay closer attention next time.
