Rust on Stainless Steel

I recently call Maytag about my refrigerator,stove,and dishwasher that show rust on them . I was told it was the cleaner that we used . I told the lady that we used a cleaner that was designed for stainless steel. I told them that they were only 1 year old and they should replace these appliances. They MAYTAG chose to do nothing . If there is any suits out there I would love to be a part . I will tell any body not to buy Maytag because they don’t back there product
