gift card redeeming problem trouble
I purchased 2 Apple Gift Cards, $15 and $25. I used the camera on my phone to take a picture of both codes one after the other. I only received credit for one, I believe it was the $25 but unsure as I had some credit from before. I try to redeem each one again but both show that they have already been redeemed. Yet my Balance wasn't over $40, it was $28. How do I check which Gift Card was redeemed? And how do I get credit for the missing GC?
