Help restoring in-app purchases

Fun game but dont but any bricks in the game. If you use them to purchase characters they will be gone as soon as you go back to the menu screen. Please help by giving our money back!!!!!! Or letting us restore in-app purchases. So far you have taken $5 from my 4 year old. Until this is resolved we wont be playing any other Lego apps.
