Not a chance. They can't be marked as "non-received" because it's confirmed in multiple locations... the distribution facility will mark the pallet as being on the truck, the truck will confirm delivery to the store, and the store will confirm receipt. No way one person at Target or BB has the power to affect all of this.
As for damaged units, they must be shipped back to Sony. The store will not simply be allowed to throw them away. I'm pretty sure all tech companies work this way. The company I work for certainly does. Returned damaged or DOA units not only get sent back to us, but they're flagged for personal inspection by a senior tech to determine the nature of the issue, they don't just get processed through the system.
This is just someone at a store, probably a part-time stock boy making minimum wage, trying to sound like he runs the place by babbling complete falsehoods to his friends online.
