LG Microwave - lying warranty, **** product

I bought a LG Smart Inverter Microwave 2 and a half years ago. It says 10 Year warranty on the Microwave. Today 30 months after purchase I found out its only got a 2 year warranty. The 10 years is for the inverter in the microwave. My Microwave is rusting, and we take really good care of it. This is the worst piece of **** I have ever bought. I will NEVER buy anything LG brand ever again.
