Have been having exactly this problem for a year now. Anyone have any insights on how to or what to tell Delta to fix it, or something they may have done that could have conceivably led to it working? I think I know how it occurred, but there's been no way to get the eGift cards out of my account, as they're not even supposed to be able to go in there, hence what's tripping up the website trying to query for them.
Thanks.
