A very rude Cashier at PEP store Overport

I have encountered the most rude cashier at PEP home overport Durban. This lady by the name Nyameka does not know how to treat customers let alone how to talk to people. I stood in a Q for a substantial amount of time and when it was my turn she told me to write my name on my slip And she called the next customer. The customer she called was doing cash send which takes even longer when I questioned that she gave me "a ****ty" response and literally that's how they do things and I should just deal with it. Her response was very disrespectful and very rude.....I continue to ask her why is she responding like that and she continue arguing with me from her high horse.. At that point I didn't know who is the customer and I knew very well I had right to complain. She went on and at the end she said a " mere sorry" that was not genuine. Cashier like Nyameka from overport PEP home is doing an enormous brand damage. I have been to different PEP stores nationwide and I have never encountered such behaviour from any PEP employees. PEP do you guys train your cashiers the same way across the country? Or for some stores the cashiers becomes the owners of the store and treat customers any how they want? I shop at PEP /PEP home because it is a brand I am very fimi**** with. Honestly if it was not such a big brand store I would never again shop at store nor enter the store.
