Spargs Madeira Superspar complaint

I just got a bad customer service at Spar Madeira Superspar because I used my phone(ApplePay)to pay for my products by a cashier named Unike.She said “ziyandidika ezi clients”who use their phones to pay.I then said to her what she’s saying is annoying and she should stop.As I was about to leave she said “hayisuka utsho ngeshori ephambeneyo” and I further said sisi I can report you for what you’re said to me and her response was “hayisuka noba ungandi report uright” I just left her from there.
