If you have received the empty package, the contents of the package have been stolen.

Wrong.

How can an Item be stolen from a perfectly-sealed box with no signs of tampering on the package?  You're not stating the "contents of the package", but rather "the Item missing from the box".

Hello, As indicated by our services. We are awaiting a theft complaint. Indeed, after analysis of your file, the package sent to your address was indeed of a weight indicating the presence of a product inside. Thus we can only conclude that its content was stolen during its delivery. We therefore thank you for providing us with a complaint for theft in accordance with our initial request.
