Query: Crude and cracked PIN

The item came with 4 pin with plastic molded on (Nylon). Unfortunately one of the plastic pin has cracked nylon coating. So it is defective. And the overall quality is crude. The product came with much oil coated over everything, and the aluminum blocks have sharp edges and burl on the back and under sides. The holes for the pegs are not snug. I looked at it, just not convinced that it can do a good job of holding the watch down and securely. So mounting watches on it should be exercised with care.Unfortunately Amazon would not give me the option to exchange the holder for another one, because... it is sold by 3rd party but fulfilled by Amazon. And the 3rd party vender won't give me the exchange, because.... well it was not sold by them, but by Amazon. Now I am sitting in the middle, just want to get this exchanged! Frustrating, I might have no other choice but to return it, and pay for the shipping out of pocket.
