Soul Of Halloween

At the store I was told by the cashier that I could return a costume if for any reason I needed to. I got home and noticed an " all sales final” on the receipt. I contacted the store owner and was told that " I was not told that" and repeatedly treated like a liar, along with being told repeatedly that they could not help me. Along with this the owner was rude, not even using full words in their messages to me ( yah. np. plz. etc.) and not always making understandable sentences, either seeming to be detracted or something of the like. I was given " head offices" number and spoken over, told that if I file the complaint the employee would be fired, but at the same time, they still would not honor that I was told I could return my costume So to sum it up - rude, uncaring, and very over confident. Completely unwilling to honor what their employees say and do.
