I suggest you contact eHobby and explain the situation. They're very nice to deal with, and I'm sure they can initiate the trace for you.
Not too long ago, after a long delay I received a horribly mangled package (with damaged content + lost bits) -- the package was ripped and a portion of the packaging looked BURNED. Dunno wtf happened to it. It was in one of those Canada Post "Oh snap!" plastic bags. Totally wasn't eHobby's fault. But upon contacting them with a picture of what I'd received, they proceeded to make things right.
I've always had good service from them, but that totally earned them a spot among the very best in my book.
