Pathetic Service

I went to game today to buy chips and saw that they advertise a special where i can buy 2 for R29. I took two packets of Doritos chips and wanted to go pay for it and the lady at till told my it is only for lays. I went back to the location of the chips saw that there was no Lays chips and that it was only Zimba and Doritos chip with the sign that it says 2 for R29. I asked for the MANAGER and he told me in my face that he won't give the chips for that price. This wasn't the only problem that I had with this store in the past i think the MANAGER needs to dbl check his price signage on his sales floor.
