I've contacted them multiple times now and have gotten the same response saying I need a police report over and over due to the item being "high value." Tomorrow, I plan on calling and asking for a supervisor.

Good.

If the supervisor refuses to help, ask to speak with his boss and If It's refused again, keep repeating the same process.

If nothing else changes, I might consider filing a chargeback with PayPal.

Yes, do exactly that.

It's no fault of your own that a police report cannot be filed, hence It works to your advantage with the PayPal claim.
