Please answer

For some reason Apple has taken my money without giving me it back in my refund. Sunday I applied for a refund to refund in-app purchases. I got the email that they were refunded but the money was never credited back onto my apple ID/Itunes account. Please please please someone help me, I am getting worried and frustrated and no one will help. Also, I have been resigning in and out of my account all day to see if anything will change.
