The Freezer freezes...and so does the Refrigerator!

My 6mo old LG Side by Side refrigerator has developed a problem. The refrigerator side thinks it is the freezer and is freezing everything. everything on the shelves, in the crisper drawers...everything is now frozen solid! I spoke with customer service and did everything they suggested...the temperature control is at the lowest setting, the air vents in the freezer side are unblocked and clear, and the sensors are clear, but everything is still freezing. HELP!!!
