The original user should have gotten an updated ticket automatically. If they didn't - it's possible that they are duping you. Or that they just sent the Belasco tickets accidentally. If, by any chance, their original ticket did NOT get replaced automatically, you should ask them to call the Box Office and get an updated ticket and send that to you. I don't think Box Office would replace your tickets directly without asking for original billing info for the tickets which you probably won't have.
