Charged twice for app
So I gift the this app called the chemistry buddy app and sent it and when they sent me a conformation for it being successfully sent. Then I looked on my other iPhone and it was never sent I rechecked two hours later and never sent . So I resent it again and it said free but when I look at my bill I am charged twice. Is there a way to get a refund.
iPhone 5, iOS 6.0.2, Sent to my iPhone 3g
