Nick should do right by you. He's a good guy. For redemption value, they don't know if you pulled the redemption or bought it, so they try to find an fair sell value on Ebay for your card if it had been made. Since you bought it last year, there probably weren't any current sales. Good luck with getting it resolved.
After you get this deal w/UD worked out, if you don't have to send back the Kitna & Brown I could use them both for my set . I'm sure I could find a tradeable you'd like.
