Constance and Tintswalo's bad service

I went to pick n pay yesterday (20/12/17). As I walked in I saw the boerewors rolls and I just wanted to have one, I did my shopping with my mom, little sister and my three month old son that I was carrying. As we got to the till I told the teller whose name was constance that I wanted a boerewors roll, she said she doesn't have the price . She then asked her colleague who also said she doesn't have it as well, her assistant who was packing our groceries in plastics( Tintswalo) then said something in Tsonga which I did not understand at all the only thing I understood was "do you understand what I'm saying" I then said to her no I don't understand. She then gave me a look with attitude and said OK. I then asked the teller what about my boerewors roll? Her response was I said I don't have the price , I then asked her what must I do now, she gave a deep sigh then stood up and I assumed she's going to get the price, me and my three month old baby and my mom stood there for a good 10 to 15 minutes waiting for her to come back, she didn't say where she was going by the way. She then comes back and starts handing out the price to every teller before serving us so we can go and she has in her hand freshly baked bread, so she didn't think we are in a hurry she decided to go get herself bread cause what does it matter anyway. She tags the price and as we leave the assistant(Tintswalo) says to Constance I was telling this girl to go get the price tag,i then turned back and interrupted her and said I don't speak Tsonga, I only understand very little and I didn't get what you said that's why I told you I don't understand. I then asked her for her name since she didn't have a name tag then I left. If I go back and find those two ladies I would not want to be helped by them. It's festive season we are all tired I get that but they could have handled the situation differently, I assume Tintswalo was asking me to go fetch the price tag, I'm carrying a three month old baby .........a little courtesy would do. Had I not asked they would have let me go without the boerewors rolls. That was the worst service I've ever had and being an employee in the service industry I know what good service is.
