I need a refund

If you are having problems redeeming a gift card, review the possible reasons and suggestions listed in this support article --> If you can't redeem your Apple Gift Card or App Store & iTunes Gift Card - Apple Support

Also realize that you just posted that card's number to where the entire world could see it. :-(

Hi there,

We are an Apple Users forum, not Apple itself so we cannot help you get a refund for your gift Card. I suggest that you Contact - Official Apple Support for further help and assistance at a time they’re open
