Worst customer service

I got the WORST CUSTOMER SERVICE BY NONHLANHLA M AT PICK N PAY,GREENSTONE.This lady was working at the tills of lottery,she was very very rude and her manner of approach is completely wrong,I overhead her refusing to assist customers before us then when we came she also tried refusing to assist us and she gave us a very terrible attitude,she told us that it is not a must to assist us,she doesn't deserve to deal with customers with that approach,J hope something is done with that lady,Nonhlanhla is extremely rude.
