Rusted Cars

We recently purchased a BRAND NEW SUZUKI SWIFT, and were disappointed to find rusted brackets on both driver and passenger seats, which attaches the seats to the car. Since purchase, and after countless communication, Suzuki refuses to cancel the deal, and with recent communication from them, they are making a Brand New Car that is Rusted our problem. Why would one except firstly faulty goods and be refused cancellation when a problem of -rusted parts- are found on New items? It makes me think that new parts and proper inspection is not been done on new items that consumers are buying. After the recent confusing and contradictory communication, could this be a problem they are trying cover up and we the consumer being pinpoint to take the blame?
