Mr Price Standerton needs to train staff and update their system

My partner and I went to Mr Price Standerton on 26/06/2022. We were standing in the que for about 20minutes as it was very busy and there was only 2 cashiers available. When it was our turn to pay the lady struggled with her computer to scan the items as the marked down prices was not updated and the computer wouldn't accept the scanned red stickers. My purchase was over R3000 and that was only half of my purchase she started the process of scanning over again for a second and third time. Another 30minutes have passed and only then a manager/someone with an override card decided they will come and help. Then the lady told me she had to scan all the items AGAIN for the 4th time. I left everything there and left, they wasted over an hour of my time with untrained staff and not updating their system. The shop lost a big sale from us yesterday.
