Saks Fifth Avenue

I purchased the shoe over a week ago. Paid extra for shipping faster. Received a size too small. Drove to the nearest store. An hour and 20 minutes away. Had to have the shoes resent. I received used worn shoes. Absolutely appalling. Hair in them stuck in the cracks, inside the shoe that I wiped out. scratches, sticker worn, stretched out. Pad inside coming out. I was not guaranteed I can even receive a new pair upon returning due to low stock. And was told it could be May till I receive. This is beyond upsetting. I had then for my birthday and an event and won't even have them. But ontop of it all USED. How does this happen? I'm hoping to hear back soon to resolve this matter.
