Lazy staff or false advertising??🤔

I visited your store in Atlantis Mall two weeks ago looking for sun glasses I saw online. Online it showed that the store had 3 in stock. When I got there they did not have any. I went yesterday again, because online it advertised that the store had 7 in stock. When they checked their system the girl said their system showed they have 8 in stock. She scratched in an open box behind the counter that apparently came in and could not find anything. She looked very irritated, because she had to scratch in the box. Eventually she said there is nothing in the box, but they have lots of boxes in the back that must still be unpacked. They had the audacity to say I must come back, because they can't say when they will unpack it. I had to ASK her to take my number and phone me when they unpack. Bayside and Tablebay Mall staff always go find the stock when a customer ask. Atlantis Mall is actually shouting to world that their stock lay in boxes for more than 2 weeks, before they unpack. This in unacceptable; for the customer and I am sure for the owners as well. I saw the ideal headbands that I needed last week in the box behind their counter, so you actually are missing sales due to them not unpacking stock. Their accessories racks are empty compared to all other Mr Price shops.
