Chic Home Isabella Duvet Cover Set

I ordered the champagne comforter set and it arrived in THREE different colors: sheet set white, comforter a pale olive greenish, and the throw pillow ivory. I contacted Wayfair and I could not make the woman understand that it wasn't that I was dissatisfied with the color, but I was dissatisfied because it was THREE DIFFERENT COLORS! I asked if I re-ordered the item would it arrive the same way...three different colors. She took the item number and said "Yes, that's the item number for the item you ordered"...which told me nothing. So one can only assume that what they fail to tell the consumer in the item description is that you can choose the color of your comforter, but you get an ivory throw pillow and white sheets regardless! And I wouldn't recommend the champagne color. My idea of champagne is a more golden tone of ivory. But this comforter I'm looking at is definitely NOT that color or anything similar. It's more of a khaki / very pale olive green.
