SAMSUNG 55" LED TV Cracked in Box

Purchased a SAMSUNG 55" Curved LED TV from a large Samsung dealer/ retail store SAVE HYPER Pietermaritzburg, during Black Friday weekend sale. The store opens the box and allows you to view the TV. I signed a document confirming the satisfactory condition of the TV (They obviously are aware of defects experienced). After this the TV was handled by the staff members and put back into the box. (how do I know TV was still in good order, as this wasn't done in my presence). TV was loaded into the vehicle by staff. Less than two weeks later, I moved into my new home and unpacked the TV from the box, carefully following all instructions. I noticed a mark on the screen. I switched TV on and found that the LCD is cracked. The store refuses to exchange or refund the TV. They say that they have contacted SAMSUNG who have tested the TV and can not determine the number of hours the TV has been used, as the damage to the screen is extensive. This absolute nonsense!!! The plastic is still on, the remote hasnt been used. No connectors or antennae have been plugged on! Not rocket science, just a pair of eyes! Firstly the store has put their verification document in place, because they are aware of this problem. Secondly I was not the only customer with this problem. Yet I am now left with a broken white elephant!!! I have just begun buying appliances, and sadly all items purchased are SAMSUNG! This is how you welcome first time customers??? I want a new TV or a refund!!!
