Samsung Refrigerator — defective piece supplied

Address:

Bilaspur, Himachal Pradesh

I purchased a RT-26RH refrigerator on 11th April 2014 from Amit Electronics Bilaspur (HP) The delievery was made at my home. After 2-3 days a dent was detected on the door of the fridge.The dealer when informed refused to replace the item.Will the company explain the fault of the poor customer? Why he should purchase a defective item by spending a big amount?
