I received my order today and I was sent an 8 piece comforter set instead of the 12 piece that I ordered. I was a little annoyed at first but when I called customer service the lady was super nice and very apologetic. She put in a new order and it only took 5 minutes. Normally any time I had an issue with an order being wrong from another place, it's a hassle. I was very impressed and even though I have to wait another week and a half for my order I am still a happy customer of wayfair. Mistakes happen. 
Also, the comforter was really nice and is great quality.
