I got off the phone with Target and they insisted that I needed to call Disney. They did send me a $5 gift card when I mentioned the fact that I seem to always end up having to do the leg work when a Target order has issues (they wanted me to call USPS when they couldn't find a DVD I ordered).
Then I called the disney gift card number, I talked to Joey who was very helpful and looked up all the numbers I entered for the day (he was able to bring up my DVA info too). Said he didn't see any record of that particular gift card being added, but said he'd have the gift card money put towards the DVA. Told me it could be the end of the day before it shows up, and it's not there yet, so who know.
