The best thing you can do is change your name. Emailing for that issue doesn't help. I emailed, and never got a reply. ^^^ I wouldn't waste your time.
Change your name... That's pretty much the only way you can solve it. Change your name, add your current name or unlock the chest. Then, change your name back.
