You shouldn't wait for a call... just go to the store and check or check a different LV store. I think the grey inclusion bracelets are starting to arrive at most of the LV stores.
I exchanged my GM Grey bracelet for another one at the Rodeo Dr. store yesterday but I still need to do an exchange on my PM Grey bracelet still since it has a brown spot inside the bracelet. But, I think the brown spot is actually one of the white crystals turned upside down with it's point showing upright in the bracelet. I think the back of the crystals are coated in brown so that the color of the crystal reflects better.
