Samsung side by side fridge poor quality

I bought a side by side fridge 5 years ago. The warranty ended 15 December 2019. I could not buy a longer warranty. Now on the 2 January I see there is rust a round the water dispenser. I have had my LG for 15 years and no issues or rust!!! I would not buy a Samsung fridge. I live in JHB how in the world can it rust in 5 years!! I would not buy Samsung as it is clearly has a manufacturing defect.
