Surprised and Angry

<p>I was surprised when Welkom Ackermans refused to exchange my niece's shoes without a slip. I bought the shoes at Randridge mall Randpark ridge but unfortunately the size was small for my niece and my sister had to go and exchange them, my question is how come when I exchange anything at any Ackermans in Johannesburg I get help but when my sister goes to do the same process in Free State she gets a different perspective. Why is that?</p> <p>The shoes still had a price tag on them.</p>
