In-app purchases BROKEN. Can't open next set. – Activity Puzzle for Kids 2 Review

Purchased the first set of 20 and now they show unlocked - but every time i click on one it asks me to purchase the next 20, and the puzzles don't open. I have rebooted my ipad2 and reloaded my purchase history. I want my money back for the in-app purchase. The "app support" link is in German and full of elicit dating website links.
