Carrelage mural Stella

I love the design, but I was very disappointed to receive these tiles and have gotten the gray and white instead of the black and white. On the website there was a mix up between the pictures and colors, but I spoke to a representative who assured me that if I ordered the tiles labeled black and white, that it what i would receive. I was not very happy to come home to see a gray and white shower floor instead of a black and white shower floor. I was unable to open the tiles before the installer installed them and now have to deal with this mistake.
