Bottom Barrel Customer Service

I am so disappointed by the service I received at PnP Boulders Midrand. I went to the store to grab a few items and then proceeded to pay at the kiosk. I then requested cash back of R 500, the cashier, Alina Mohapi handed me R 300 and told me "otla ema, ke na le R 300". I was shocked that that's how she spoke to me, with no customer service etiquette, professionalism, and politeness. I asked her if I can't reverse the transaction after being dumbstruck by not only what she had told me, but how she said it. She told me that there was no way for us to reverse the transaction. When I asked her how long I will wait she RUDELY and NONCHANANTLY rep**** that she has no way of telling of much money she has in her till but was surprisingly able to give a customer that paid after me cash back. From then on it was a back-and-forth between herself and me. She showed NO remorse for what she had done and how she spoke to me, even when the manager, Berlinah stepped in to intervene. There was no apology from Alina Mohapi. I am beyond appalled by the manner in which PnP employees talk to the people that pay their salaries, i.e., customers. I hope that no one EVER experiences the HORRIBLE and DEGRATORY service from Alina Mohapi and her kind. Sincerely, Disappointed.
