Itunes gift card already redeemed

If somebody else redeemed it you will have to ask that person when they redeemed it. If you redeemed it onto your own account and for some reason you want to know when you did it, you could try contacting iTunes Support and see if they can/will tell you when you did it :

- go to http://www.apple.com/support/itunes/ww

- click on your country's flag (the country where you live, and which is therefore the country on your account)

- click on Contact Support towards the top right

- click on Get Help under 'Talk To Us'

We are fellow users, nobody on here can tell you who redeemed them and/or when they were redeemed - and iTunes Support can only tell you things about your own account, they won't give you any information about other people and their accounts

If you redeemed it onto your own account they should be able to confirm it. If somebody else redeemed it you will have to ask that person.

It was most likely redeemed by someone else as the other guy said. Try to ask the person who you got it from if they had redeemed it or where they got it from.
