I bought a ITunes card for 50.00 and tred to use it but it said it had been used ?j

Try signing out of your Apple ID and then back in again in case the balance has been applied to your account but isn't showing correctly.

If you bought an iTunes gift card voucher which you cannot redeem then you should first try If you can't redeem your App Store & iTunes Gift Card, Apple Music Gift Card, or content code - Apple Support in case you are either entering the code incorrectly, or the card wasn't activated. For activation issues seek redress from the vendor.

If you have sent the card details to someone else as a form of remote payment, or have bought a card that has already been redeemed, then you have been scammed. See iTunes Gift Card Scams - Official Apple Support for more information.

This is a user to user support forum. No one here can help directly. Have you contacted iTunes - Official Apple Support as recommended in the support articles. Did you make the purchases from a reputable store? Do you have the receipts?

If this had happened to me previously I would be tempted to Send App Store & iTunes Gifts via email - Apple Support in future rather than purchase physical cards.

As posted previously use iTunes - Official Apple Support or links to support from If you can't redeem your App Store & iTunes Gift Card, Apple Music Gift Card, or content code - Apple Support.
