Query: Sent item that had already been returned.

I received the Viatek Professional Bark Stop in today's mail. I followed the instructions and it never worked. I then started going thru the paper work again and found a note from the previous owner "Worked for one day and then quit." Obviously I was shipped an item that had already been returned....and NO I didn't not ask for a replacement.
