Query: Received two right-foot slippers

My family has purshased many items over the years from Amazon, from books to TVs. This is the first item that we are unsatisfied with.Previous reviewers have said the top of the slippers are too tight. I ordered a pair on the larger side for my wife in anticipation of this potential problem and they were still too tight - but OK. Next, my wife said they didn't feel right and kept switching them from one foot to another. She soon discovered that we were shipped two right-footed slippers. Are you kidding me? Now I finally get time to return them and I find out that I have to return them on my dime because the "return window is closed". Comm'on I bought them for my wife for Christmas and it's only the beginning of February. I will never buy footwear from Amazon again. Too much risk and hassle. In the end, these slippers are not as nice as slippers you can buy at half the price just about anywhere.
