Bad service

We went for grocery shopping around about closing time, we shopped and saw a special of brown sugar for R49.99 but the was no sugar there and the special was valid till 1 January 2024. I ask a lady working on isles she said its out of stock there is nothing they can do, i requested for a manager who then said its out of stock and it while stock last but that is not written on the special. We were doing back and forth giving me attitude she ended up saying she will refer me to a manager as she is not, they all have no name tags but this one was called 'aunt Sara. For about 10 minutes waiting for her she didn't return everyone was looking at us as if we stole something. We finally saw them standing at the door of their office pointing at us but they didn't come to us. We decided to go to them after our purchases. We found them busy with their truck delivery stuff, apparently aunt Sara told her but she was still busy but finally they assisted us and gave us the sugar but after all the drama and the time.
