Disappointed Customer

I went to Canal Walk KFC to order Ice cream which I did via Kiosk machine and my order went through, I waited under the screen where I needed to collected and the lady directed me to the next side, as soon I get there I show them my code, and the lady that was serving there to be specific Neliswa didn't even greet and she just said where was I coz she has been calling my number, told her I was in the other counter, and Proceeded saying she has been screaming my number but I didn't come through told her didn't hear her, she continued expressing how loud she was SCREAMING there is no way I couldn't have heard, and just to minimize arguing I just kept quiet, Anitta (training) proceeded with the order however now they didn't have kit-Kat flavor and had to change my ice cream to another order, after such a rude service I had to make peace that they don't even have the stuff I ordered. But anyway I took alternative.

However I wanted to raise issue with Neliswa she is very rude, and talks about customers so rudely in her home language thinking we don't understand, making sarcastic statements.

She is there to work and she should stick to that.
