Very bad service price

<p>I had the worse service . I went to mr price loch logan to exchange 2 pants . One was R149.95 and the orther R99. I went and got what i wanted then went back to the till. Waited 20min and then when they helped me they scan the jeans the one price was R 10 and the other R20 ***. I didnt have my slip but the lable was still attached to the pants. Then they said they will not do a price over write because i dont have a slip but why the hell do i need my slip if the lable are still on??? So i had to leave without exchanging anything. And after spending time and wanting to spend more money. They will not see me again if this is the case.</p>
