Yeah, you did sent GTA V to me two times but it says gift has already been redeemed. I think you are re-gifting my copy of GTA V to other people so I don't have a chance to redeem it.
The GTA V gift I received was redeemed over 6 hours later, without a problem. I highly doubt that something like this happened as it would hurt wakka662's sales and others would have complained about it as well.
