What a rude supervisor

<p>I was sold a wrong cellphone yesterday. When i returned to exchange it today i waited 40 minutes just for a simple exchange. the supervisor said i should wait for her because she was busy. I asked if i could show her exactly the cellphone i asked for and she rudely told me that she is the one who packed those phones so she knows exactly what I'm talking. I was so mad i dont see myself going back to that shop!</p>
