It didn't occur as quick as yours but they too call it cosmetic.
I purchased a Samsung French Door refrigerator with a built in water dispense and ice maker about a year and a half ago. Literally, not even 1 month after the 12 month warranty, we notice a little rust on the corner of the ice maker. I called Samsung and they said that they consider this cosmetic and would not repair the unit. I tried several times but I got nowhere. With every passing month, the rust gets worse to the point that the white paint on the door under the ice maker is now bubbling and pealing. Has anyone else had this problem and if so, did you have any better results dealing with Samsung. Their customer service is awful and they do not stand by their products. This was a very expensive refrigerator and should not be rusting. Help!!!
