Bad service

I was Served by a cashier named Tshepiso Gladys Phelane.. Not even a good morning, didn't ask for my exta savings card and was rude when I asked for cash back telling me that she doesn't have it I will have to join another que and that it's less expensive at the till ..I told her I can't perform 2 transactions. I told her to sum up everything and make 1 transaction n she said the till register doesn't allow me to make 1 transaction. .I had to pay and withdraw after...I paid for my goods n left. . It left a bitter taste and unpleasant shopping experience
