Bought coins

I bought coins but it says that it has not downloaded yet? I have waited for over 5 hours and I'm not sure why I still haven't gotten my coins? It has been taken out of my itunes account money though.

Dear ohnoitscheng,
With regard to the coin issue you encountered, Maybe it is caused by the following reasons:1.Perhaps your network was not in good connection,or you exited your account suddenly during the transaction.2.Perhaps the iTunes system was very laggy in processing this transaction.You might need wait for a longer time than usual. when you receive this message, please wait for some time,if you still haven't get your coins after a very long time,please contact iTunes support for help.
