Terrible useful life of SAMSUNG Product

I purchased a Samsung Smart Sensor microwave from Game South Coast Mall in December 2021. We were given a 2 year warranty. In August 2022, the Keypad stopped working completely. We sent it in for repairs, and it was apparently a faulty Keypad which was replaced. It was returned to us and now less than 4 months after, the microwave yet again has the same fault. We took it to Game, where they informed us that we could not send it back for a repair as we are now out of warranty by less than a month and they can't help us any further. Samsung was called and they say that even though it's the same fault that they fixed less than 4 months ago, they can't help us. What I would like to know is, how are we supposed to pay R2590 for a microwave and it lasts less than 2 years and is barely used. How can a consumer be expected to trust the useful life of your products? The fault is clearly a factory fault but we are being cheated by a technicality. @Samsung please respond.
