It is not my problem.

I went to Pick n Pay to buy 12 sachets of Whiskers Kitten food and it was market on the shelf for R59.99 and when i paid for it,it was R72.99 so i asked to speak to the supervisor and she was so rude and had told me that it is not her problem and that there is nothing she can do for me. I then asked her to refund the money back to me because i am not going to pay R72.99 for it if it is labled at R59.99 she literaly threw the money at me.
