itunes gift card
I added an iTunes gift card in the iTunes store. I used it maybe two or three times, and then it disappeared, and I'm not able to use it when purchasing new songs. I tried adding it again, but it won't allow me, because it says its already redeemed. The card was for $50, and I'm pretty sure I only used it a few times, so I should have quite a bit left on the card. Has anyone come across this problem?
