Poor customer service

Hi, I'm a frequent shopper at your stores and the service I got today was appalling. I'm heavily pregnant and needed a few essentials at your store. Being heavily pregnant I tried paying at the kiosk and was told I have too many things so I need to pay at the "staff till." I too know the retail industry as I worked for Woolworths for more than 3 years.I went there and found 1 employee paying and a few other patrons who were not employees of the store nor the mall. I asked if I could pay and the cashier (Kamogelo) with a friend rudely said this is a staff till and I must wait in line like everyone else. I further told them that a person in my condition can't stand too long but he continued with whatever he was doing and even took a new customer. I called the manager (Nelisiwe Mkhwa****) who also didn't assist me much until 1 employee (Sihle Nkabinde) assisted me. This type of behavior is a disgrace and i hope the cashier will be dealt with accordingly.
