I apologize if this has been asked before... I want to actually talk to someone at Apple about my account... the problem being that I can't purchase anything from the App store because i am getting an error saying i need to sign in and update my account information. The part to be updated is the credit card security code. When I input the code from the back of my card, the the account info says it's an invalid code, and in effect my account is not available. Is there a free number i can phone to talk to someone about correcting this?
