Good shelves if they come undamaged

We bought 30 units for a wall in our warehouse. They are good shelves. However, two units came broken. The corners were damaged and could not be used. Also some of the metal frames were damaged and bent. Wanted to get two new ones, but you have to go through the hassle of returning them. I would rather just have sent photos, and gotten two new units, and then thrown the broken ones away. It's particle board, so it's cheap material. I will just take the loss rather then spend time on packing these big shelves up (with all the pieces) and returning them.
