Do not purchase a LG microwave.

I bought a microwave on Takealot, being a LG. A year and a month later it is rusted inside. Does not microwave over a certain amount of mjnutes, cuts out and needs to cool off. I reported this to LG and my request was a new item, which was denied and the small print was used to get them out off a very defective purchase. A microwave, especially being a LG brand should last years, yet I was told rust can occur if I do not use it the correct way, what would be the incorrect way. I will never purchase LG again or recommend.
