Ordered 2 pairs of shoes from different sellers. One canvas pair ran a sz smaller than stated. Sole was worn down. Must have been washed and dried and shrunk. The other pair had a rubber sole in better shape, but hard as a rock. Shoe had no give or bend to it at all. Like trying to walk on a wooden ski. There was no size or width inside the shoe. On the soul, it simply gave the number, but no width. When I tried to take a step, my foot just came up out of the shoe it was so wide. Poshmark refused to let me return either pair total cost for both was almost $50 not cheap. Tried to attach 4 photos for one shoe and 3 for the other but got msg saying you could not upload one of my files, no pics show. Says contact support. How and where do I do that?
