The Dishwasher Racks Rust within a Year - No Assistance

We bought a Hisense dishwasher 2 year ago, and now the shelves are so rusted the pin are breaking off. We reached out to Hisense to see if we can buy new shelves and no we cannot. Please rethink when buying a Hisense dishwasher as it is not a 5+ year investment. Very disappointed to need to buy a new dishwasher after 2 years.
