No don't say the package is damaged. Then the mailman will be at fault. The last thing you want to do while scamming is hurting the common man.
Just say someone stole the package. Can't you think of that yourself?

Well yes I did think of that but I know exactly what’s gonna happen with that. They’re gonna say we can’t help you until you report it to the police and they investigate it. So I don’t really want to go down that route.

okay here are the steps
1. Say someone stole the package
2. Investigation will occur. Make sure you are on good terms with your mailman
3. Wait some time and you will get a refund

you can do that (which id recommend) or "return the item" and its not your fault if they lose it during return if something you're saying is this heavy surely the box can "accidentally break" meaning that the item is lost forever
