Arrived used for the second time.

I love Melissa sandals. The product is good, but it arrived used for the second time. It is poor store management.

Used shoes
Size: 10 Little Kid, Color: Glitter Clear W/Strap, Size: 10 Little Kid, Color: Glitter Clear W/Strap
If I could give this zero stars, I absolutely would. I ordered these shoes expecting them to be brand new since I paid full price and never selected any “used” option. What I received instead were clearly heavily worn shoes there were visible signs of use that you simply wouldn’t expect from a new product.
