Query: I was sent a used Diaper Champ!

I cant believe I was sent a used product!!1) The box seemed to have been ripped by a previous owner and then was taped2) The plastic bin had scratches all over it and I found someones hair inside it!3) The dispensing unit had scratches on it!4) There was signs of the items having been cleaned up, it was oily inside the bin!5) In order to clean this you need to twist both of the knobs on its side counter clockwise... best of luck opening it. It's hard to move the knobs let alone twist them.$40 for a used diaper champ... not worth it.
