Superbalist Sends Wrong Order and Now Refuses to Refund Me

Superbalist sent me the wrong item. I bought a coat and they sent me a random dress. If this wasn't bad enough, it is not three weeks and I am still waiting on my refund for the coat I bought and which they failed to send. Another big company that couldn't care less about its customers. Ten emails, three calls to them later and Superbalist has effectively just ****** my money, and are getting away with it.
