"The company assumes responsibility for delivering the goods to your specified location (DDP terms).
In this case, an empty box would likely be considered a delivery failure, and you'd be eligible for a full refund."
Search for something like that, they will probably have to assume that they didn't ship the correct item, try to see if they pass the responsibility to the carrier.
If they claim that they ship the item and carrier has POD, then u will probably ask proof or any backup that backup of their claims, photos or something, because u didn't receive ur product.
If all this doesn't work, proceed with a bank dispute and provide evidence.

I see your point, thank you for the clarification🤝

but if they just throw in mailbox DNA is still good option?

Depends on their terms & responsibility.
DNA is still good option, but EB is more common with lightweight items, because there is no actual proof that the item you ordered was inside the box due to weight of the product, they can't backup their claim.
