Spoiled food and no refund we got sick

Good day, I am writing to formally raise my concern regarding the repeated sale of spoiled and expired food at Pick n Pay Gordons Bay. I shop at this branch almost daily and generally rely on it for my meals. Under normal circumstances the food quality is acceptable; however, since the festive season the standard has deteriorated significantly. Over the past few weeks I have experienced the following: I purchased a chicken mayo vetkoek which, upon opening at home, contained rotten lettuce and tomato. I returned the item the following day to show staff, but the matter was brushed off with only an apology and no refund or replacement. I later bought a calamari sub, and once again the calamari was off. The response was again only an apology and “thank you for letting us know.” Today I purchased a macaroni loaf which is clearly sour. I did not return it, as previous experiences have shown that complaints are simply brushed aside without any resolution. In addition, on Christmas Day I ordered a baked milk tart, but instead received a Swiss roll milk tart. The packaging had more than one sticker on it, and it was clearly past its intended use-by date (meant for the 24th). Although it smelled acceptable at the time, all three of us who ate it became ill for two days afterward. I lodged a complaint via the ASAP app but have still not received any response. I want to stress that the staff are generally friendly and helpful; however, friendliness does not make up for selling expired or rotten food. Simply apologising without offering a refund, exchange, or corrective action is unacceptable—especially when customers rely on this store for daily meals. I am extremely concerned about food safety and quality control at this branch and ask that this matter be taken seriously. I would appreciate feedback on what steps will be taken to address this issue and prevent it from happening again. Kind regards, Richardo Roccon
