While most of the transactions go smoothly, sometimes an answer from Apple or our servers might be slower than usual or might result in errors. Please wait some time and see if they will arrive. If this doesn't help, quit and restart the game. Your gems should be credited to you.
Cydia repos or 'apps', can mess with this creating the problem, if you are jailbroken, un-jailbreak or disable tweaks to make the purchase.
Apple doesn't allow App Developers to see purchase transactions, so Supercell has no way to verify attempted purchases if the transaction does not make it to Supercell's servers.
If after a day of waiting, you do not get your gems, contact apple to request a refund. There are links in your e-mailed invoice, or purchase history within iTunes.
