Webstore Jedi temple guard pack

When I wanted to get for free the Jedi temple guard pack, I thought I could get it via PayPal, but once they asked for my permission, I wasn't able to use the promo code at all and they charged me the 12 euros. Is it possible to get a refound of the pack ? I still haven't used it in game.
