Men's Fanatics Black Pittsburgh Penguins Core Primary Logo Flex Hat

I bought a medium/large cap. Turns out it's too big. I've tried a couple of times to get a return code on this item but I get nothing. I thought Walmart had a better return policy than this. I've been sick for a couple of years. I checked my other hats and they are all too big now. Apparently Walmart is going to make me keep a new hat that I can't wear. Not cool.
