Walmart continues with the Game bad service

Walmart South Africa where advertising Vannemei prawns for R99.99 per box until 23rd March 2026. I went to the Boksburg store yesterday as well as today to try and buy only to be told that there is no stock and unfortunately it is tough for the customer. (as per Refiloe at customer service) Game has been a regular culprit for advertising things and then not having stock. Does this mean that Walmart is just a Game store rebranded and continues with the bad service?
