Sears

I purchased at Sears.com a Kenmore 18 cu. ft. white refrigerator. It does not keep cold and then too cold in the Freezer! It has a Frost build-up in the freezer like it is an old model that needs to defrosted by "hand". They say I can't return it. I bought it on-line on October 19, 2015. They couldn't deliver it until 11/06/2015. They say 30 day return policy and count from when I purchased it, not when I actually got it! I want Sears to pick this up and I will get a different one.
