Brand new refrigerator...freezer works great,...

Question

I have a brand new Frigdaire 21 cu. ft. refrigerator. The freezer temperature is perfect, but anything placed in the fridge spoils or goes rotten rather quickly. The temperature in the fridge is room temperature...approximately 70-75 degrees. I did go to the Frigdaire website, but their troubleshooting guide didn't help me at all.
