Kiosk cashier

I went to shop by Jumbo Cash n Carry Crown mine in jhb, I must say their customer service is pathetic really, we were by the tills waiting to pay, one lady that works there came to us and said we have to go to the kiosk to pay, When we got to the Kiosk where we were sent to pay, there was this short lady by the Kiosk that disrespected us in a way i cant explain in words, telling me next time when you have things more than 10 you musnt come this side, at that time i only had about 8 items, i tried to explain to her that we were by the main tills when one staff member sent us to the Kiosk so thats why i was there,and that my items were not up to 10, the lady started swearing at me speaking Pedi with the other work mate and started talking to me with an attitude saying I was just telling you this so you know for next time when you have a lot of stuff dont come here but i was like my items are not even up to 10 so why are you telling me this, yoh the way this lady was answering me, 1st her attitude was that stinking attitude and the way she was talking to me, if you could see the disrespect on her face, so disappointing honestly, customers deserve to be treated better, why will i be told by your staff member to go to the Kiosk if im gonna be insulted by the cashier at the Kiosk??? Doesn't make sense
