Game - Bad Customer service experience

I am not happy about the customer service from Game Jabulani Mall in Soweto. My wife R Motsoeneng bought a blender on 16/02/2025, 2 months after it stopped working. She returned it to the store in mid-April, they told her they will check it and call her once everything is sorted out. She was never called and she decided to go check in May and she gets there she was shown a much older blender and they claimed its hers. She refused to take it because hers was new she just used it for not more than two months. Yesterday 19/09/2025 she went again still she never got any assistance. See the attached and insert below
