RUSTING DISHWASHER RACK WITH NO CUSTOMER SUPPORT!!!!

I purchased a Hisense stainless steel dishwasher from Hirsch's on the 24th June 2021, the dishwasher has a 2 year warranty and according to Hisense my warranty is over before my 2 years have lapsed, why I have no clue... The reason for my complaint is that the bottom rack is rusting on every joint. I've sent emails with no response , Hirsch's claim I need to purchase a new rack for R1000. I've received 1 response from Hisense after weeks to say its out of warranty and to contact a certain lady, when I called the number provided it was for TV repair center. Regardless of the warranty surely a rack in a dishwasher that uses water constantly should NOT rust at every joint?? Or is this just the quality of your products?
