Rude pep store cashier

Lerato cashier at pep store at spruitview shopping center. The lady is rude first it was the nasty looks she gave me and my grandmother. Then wen I had to pay she was not assisting with the card swipe machine and then told me the machine doesn’t take capitec debit cards. I went out to spar next door to do cash back with the very same card and came back to pep to pay and there was a another lady paying with capitec card and it worked. I asked why is her card working she continued to be rude and I got rude too because I’m a paying customer. All the staff at the shop even the security are saw . Time was 17:15 Thursday 18 2019 my cell phone number is+***
