Query: BEWARE! USED BATTERIES!

I ordered this thinking it was an attractive price, but was sent an obviously used battery (package had been cut open, exterior of battery was scuffed, contacts had worn spots from being in a phone). I tried it and it didn't take a full charge, so I returned it (at least the return was easy), and today got ANOTHER obviously used battery. What is going on here, Amazon???
