I ordered 4,000 silicone wristbands. Order said 4 colors. The supplier sent me an image and the colors looked right on my screen but the black was actually a navy blue. The supplier said they made a mistake but I had said the image looked good. I had ordered trade assurance from alibaba and opened a claim stating I asked for black. They said that I should have known the color codes and that it was my mistake. They don't allow you to leave reviews of the suppliers and they don't follow through with protecting the buyers.
