I was making lay-bye for my kids clothes at the store at around 17:00 on the 18.04.2016 a cashier by the name of Lindiwe and her supervisor I didn't'see her name in fact she was not wearing a name tag that lady shouted me in front of other costumers telling me how I'm going to pay the lay-bye she doesn't care if I'm working or not but the way she looked at me I can't afford to pay R3000 labye she really humiliated me I was not happy about the service .
