Rust on Refrigerator DoorsiiiI M

My refrigerator doors have rust on them.  I had them a little less than a year.  I contacted Sear, was told that this was considered cosmetic a d was not covered by my warranty. I used the stainless cleaner that was given to me in my refrigerator.  This didn't help. My doors now look like they are always dirty.  Any suggestions would be appreciated.
