PICK N PAY untrained staff

Bad customer service. They first help all of there staff and let all customers wait in line and u was in a hurry to make a small transaction for a Pie and a Monster. The cashier is untrained and has a stink attitude telling me how to use my card and the more u tell her i have to Tap and Pay on my FNB card for the transaction to go through the more she tells me yes but you have to insert the card. When i tell them to call the manager she just sat there sucking old food out of her fat face looking around. I am a busy person and i am in a rush to a job and don't have time for rude people ant stores. The manager came after a while and i explained the problem then he looked at me like im crazy and then decided to try again and told me to insert my card as i told him twice a have to Tap and Pay for the transaction ro work. So i told him to leave the stuff and i will launch a complaint at Hello Peter and he said yes go and do so. I am very unhappy about this as they try and tell ne how my card works.
