Accidently bought the wrong service..

Hi, uhm, I made a superfail and bought character recustomization thinking it was a race change.

Is there any possible way I could like.. take the recustomization back, and then pay for a race change instead...?

Or am I screwed for being an idiot..

battle.net confused me with "appearance change" yeah.. dunno how I fell for that, but it's late here.. >.>
