Disgusting Service

Very very disappointed in the service I received from Pick n Pay liquor festival mall,actually atrocious...the cashier Francinah Malatjie was the worst I have experienced and showed clear lack of customer service,I used my card for a cash back...she rolled her eyes and asked if my bank had not taught me how to withdraw,then had the nerve to swipe her personal smart shopper card with my purchases...raised her voice at me even after I had asked her to calm down...Pick n pay has truly disappointed me here...can they cashiers be trained better
