Someone ripped open the package, opened the box and took the razor, then it was delivered to you?
I sold a book via eBay that had the same thing occur. The box was essentially shredded, the book must have fallen out in the mail. We sent it via USPS. They delivered the box anyway, with a note that basically said "Our bad, crap happens. Nothing we can do. Call us here if you want, but we won't do anything." Supposedly the mail machines did it... The buyer took a picture of the note when he asked for a refund. Next time, I'll do priority mail.
