Rust on the freezer that bosch doesn't cover

I bought a bosch fridge/ freezer.it wasn't even 2 years old and started rusting on the freezer door.i contacted bosch they said that they don't cover rust.how man you pay alot of money to buy a good brand but there service sucks really.now I'm sitting with a fridge that costed me over R17000 that is rusting and bosch or the shop that you buy it from doesn't tell you this things before buying it.bosch your after service is terrible and would recommend anyone to buy this brand really.i would never buy this brand again.
