Question marked as
Can you try to return the Apple Gift Card to the reseller?
I'm afraid, the official Apple Support can not help with this issue:
...
If you see a message that says the code must be redeemed in another storefront, the card was probably purchased in another country or region. You can't redeem Apple Gift Cards or App Store & iTunes Gift Cards outside of the country or region of purchase. For example, if you bought an App Store & iTunes Gift Card in France, you can't redeem it in the App Store in the United States.
If you need more help, contact Apple Support.
