Recently I bought some credits via the in-app purchase system on my iphone. But I didn't receive any credits since the system said I could not connected to the server. Later I closed the app and reopen it, entered the store, a message pop up and said my purchase is successfully. But I didn't receive any credits! I tried to purchase again, then I could only get the credits which I purchased second time. I was indeed charged for the credits purchased but didn't receive them. Would please advise how could I get those credits back? Thanks a lot!
