Samsung Electronics — 26 cuft bottom freezer refrigerator

My 26cuft bottom freezer refrigerator for the last 2 years refrigerator part freezes up and melts down the back wall. The bottom of the compartment fills up with about an inch of water under the vegetable bins and visible ice is exposed through holes in the back wall. This an obvious flaw with the product. The temperature recently went from 37 to 52 degrees in the refrigerator.
If the defrost capability worked in the refrigerator this would not occur.
After calls to Samsung and searches on the internet for solutions I found this to be a very common problem which Samsung is not taking any financial responsibility to repair.
Is there anything samsung can do about by $146.00 repair bill not counting the loss of food and the time spent defrosting a product that is supposed to self defrost, time on the internet, time calling Samsung, and time arranging for the repair?
PLEASE HELP ME AND OTHERS WITH THIS PROBLEM
