Bad Customer service and rude staff

on sunday the 11 June 2019 i went to debonairs Dube in Soweto to buy pizza, a lady by the name of Nomfundo Mchunu was by the tills and I ordered a Large sweet and sour rib for R64,99. when she was giving me the machine to enter my pin i realized that the amount is R20 more and i asked why is it like that, since i ordered the large pizza that on special. she started lashing out at me saying i never mentioned that i want the rib one, i just said sweet and sour and there are 2 types of sweet and sour pizzas which is the chicken and rib, so i told her that maybe she didn't hear me properly and the other thing is if there are 2 different types why didn't she confirm which on i want and she just assumed that i want the chicken, she was so rude she shouted me in front of customers telling me how she deals with this everyday and i can't debate that, and insited that i only mentioned sweet and sour and said she'll change it. i was so angry but i stayed calm, they gave me the order which was supposed to have been changed, when i got home i realized that they still didn't give me the pizza that i requested. if it wasn't that it was already late, i would have went back, but i must say none of your customers deserved to be served by a self centered women like Nomfundo as she looks down on customers and speaks to them rudely. I'm disgusted by her behavior and i hope she goes to training for customer services s****s.
