Apple gift card sent to wrong email address

I bought and sent a gift card to a friend. After getting the notice that the card was sent, I noticed that the email of the recipient was incorrect. How can I have the card sent to the appropriate address? Apple.com offers no area to email inquiries to help with this unique (and stupid) issue. I would love to call, but I am a deployed military member and can not stay on the only available satellite phone for a length of time. I called once and it took over 30 minutes for the assistant to say he would help me. I have not seen a change in the gift card status. How can I fix this problem via email/online?
