Hisense... superior price inferior quality!!

Dishwasher rack started to rust in the first 6 months of purchasing. There warranty does not cover this. Does not make sense that you produce a product that cannot withhold water and rust so quickly. Two pins rust through, they broke off. We have requested a new rack but they don't have stock and we need to replace at own cost. Hisense HQ does not reply to any mails that you send. I have 3 reference numbers... no response.
