Bad attitude from Sibongile

I went to buy school t-shirts on the 25th of August and the service i got there was shocking. So i took 2 long sleeved and 2 short sleeved for my sister to fit because she is a chubby girl and im not sure of her size. She fitted the 1st shirt and the size was big, she gave me the shirt so i can fold and put it back in the plastic and when she gave me the 2nd shirt to fold, one of the ladies who works at Pep started shouting in my direction like 'sorry, you cant fit more than one shirt'. Then i explained to her that i was not sure of the size and she told me i should have asked someone for help with the size. I then explained to her that there was no one by the school uniform section hence i just took the sizes i thought would fit her. Her response to me was that 'you should have came looking for us, we can't be standing there for you'. I then decided to leave the store since it was clear that you don't take your stuff to customer service workshops. When i related the story to my mom and described the lady, she said her name is Sbongile and she is known for being rude to customers. Please educate your staff about the importance of customer service and more e specifically being visible at the store so we can be assisted. The only person who was visible there was the security personeel who assited me to open the fitting room since they keep it locked. I ended going to Jet and got what i needed without anyone being rude to me.
