Stone Lain Grace Square Stoneware Dinnerware Set, 12 Piece Service For 4, Plates and Bowls Dish Set, White

I received a set of the black and 2 of the dinner plates are grey not black . Can I get the 2 plates exchanged ? Or return everything is will be hard

Is this oven safe, if so to what degree? Also is this returnable ?

Do they scratch easily?
