Mr Price Carolina Mpumalanga

The service I got at Mr price Carolina in Mpumalanga is so bad in fact I'm still shocked of how the cashier treated me, she was so mean I've never seen such before. She shouted and me and when I asked her why is she being like that she commanded me to shut up, she threw slips up and yelled. I don't understand why she was furious hence I brought the required slips for exchanging items when she gave me change she gave me a R20 note that is not of good quality and has oil when I refused to take it she rolled her eyes as if I'm the one who is wrong. It's unfortunate that I didn't get her name because she was not wearing her name badge. I asked her where should I rate her service she said she doesn't know and she asked her manager and she also said she doesn't know. I am so offended to be shouted at like a kid. There is no sense of respect or humanity.
