Faulty appliances becoming a norm

I have purchased an oven and hob set, a fridge as well as a oven hood from pick n pay hypermarket in Princess crossing. All these goods were bought last year and they are all broken. I reported it to defy and got reference numbers in December but nobody came to assess the appliances. I then followed up again I'm Jan and that's when they came to assess the appliances. It's been more than 3 weeks waiting for their help. My meat even got spoilt because of the lack of quality goods from defy . This brand used to be good but now I discourage anyone who wishes to purchase it to strongly not waste their money. It's not like they don't know their products are nonsense, they just enjoy making money out of us and not fixing their appliances when they broken. Better yet replacing them rather... I sincerely hope you guys lose business because this is getting out of hand now
