Faulty items

On the 7th of July 2022, I bought the R 350 combo, kettle, two plate and iron, on the 10th, the stove stopped working, went back, it was swapped, 10 days later, new stove also stopped working, went back, the lady at cigarette counter told there's nothing they can do, I asked her about the guarantee, she said they've already swapped the stove, I asked for manager who came and told me the same story, I also asked her about the guarantee, she couldn't answer, and just took the receipt and stove and came back gave me money for the stove, I then asked her how about the other items, what if they also give me trouble after she took the receipt, on the 25th August the kettle stopped working, and I can't take it back cause I have no receipt, I stay in denny Dalton, I go to ulundi to do my groceries, why does boxer sell us things that don't last, I've bought stoves from boxer but never had such heartaches why now, now I'm without a kettle, in less than 3 months.
