Terrible Shipping Experience and Poor Remedial Action by Dell customer service

I ordered an LG 55-inch 4K Ultra HD Smart TV OLED55C7P UHD TV through Dell. I received the item this morning. The box had a very large rip that the delivery driver pointed out to me. (the package even stated the shipment was loose on the receipt) I decided to open the box, with the driver present, the TV looked fine, I was in a rush to get back to work, so I decided to set it up when I returned home. When I plugged in the TV  the backlight would turn on and shut off right away.

I immediately called Dell customer service, explaining the problem, they said it was most likely a manufacturing issue, and I needed to call LG to be able to complete the exchange. After explaining what happened to LG, they said it was likely a hardware issue due to a drop. I asked them for a ticket number to give back to Dell to avoid having to pay a restocking fee, and got nothing from customer service but a run around between departments. 

How hard is it to complete an exchange when I've had the TV less than 8 hours? 

Help resolving this would be greatly appreciated.
