Rotten/expired meat

I have been a customer for SPAR (Mills - Hayfields) since it opened or relocated to its current location. This afternoon around 16H30 I as often passed by SPAR to buy some beef steak to grill at home. I bought 2 packs or their prepacked rump steak. As my daughter was seasoning the said steak, she called me to show me that the meat was rotten and expired last week. The steak even had a terrible and unbeareable smellOn the packed, it is written that the steak was packed on the 27/08/2023, which technically means that it has been in their fridges for almost a week.

I am very dissappointed.
