Problems at the store

[Laliux]

Yesterday I bought the über pack at the store but when I selected the pack and put the password of my apple account on the iPod screen appears the word 'purchasing' and suddenly changes and appears the word 'cancelled' but I didn't press anything, later I tried to buy the same pack but I can't 'cause an announsment appears on screen saying I already bought that pack so I pressed the button to get that pack and nothing different happens first appear purchasing and then cancelled. The worst is that I don't have the characters of the packs and they took the money of my account.
What can I do????? I love this game
