Easier to put a camel through the eye of a needle than get your refund for a defective item

After spending close to 10k on some items. I currently back at the store for the 3rd time in one day to return ONE substandard item. I have been sent back because the item was out of the original packaging, then upon returning, I was sent home to revassemble the purchase, take a video and send it to them for review, mind you the item was delivered yesterday afternoon. I am being told that they cannot refund me because I assembled the item, how would I pick up the defect if I don't assemble it? I'm still here waiting for Louis instore for close to am hour now. Worst experience Ever.
