Bade service at PICK N PAY Southdowns

We go to SOUTH DOWNS P&P every week, yet yesterday the "manager" refused to help us, when we wanted her name, we waited 10 minutes and guess what still NO NAME, we were gifted with items and those items we cant use due to us being diabetic, the stuff was bought on someone else's P&P app and this manager insisted we must give her the invoice, we just couldn't and all we wanted was to exchange some of the MAIZE MEAL, RICE, PATATOES and small items for stuff we can actually eat, she was going on about ***** and how people commit it, we asked her nicely, she couldn't care, she turned around and left us standing there, we still do not have her name and all of a sudden the rest of the staff did not know her name, what the hell is this, working under someone not knowing her name, we spend on a monthly basis at least R 4 000.00 there and this is the help we get, we cant ask the person who gifted us an invoice as he will think we are looking the gifted horse in the mouth and trying to explain this we just couldn't get through her brains, what a sour experience, we get along with all the people there, but last night this lady was the pitts, we still dont have her name....THIS IS NOT HOW I KNOW P&P
