I have made an in app purchase of Gems, Money has been deducted but no Gems have appeared. You help is appreciated ( already reported problem through Itunes )
Me too. It's really annoying! I've logged a query with iTunes. Hopefully they'll be able to sort it.
I had the same issue with Gems and 1 off offers for skylanders on world level up. Twitter support for activision resolved within 24 hours and no fuss at all.
