Package lost in the mail

I have an issue that I'm not sure how to proceed. I placed an order on 9/19 and the seller dropped the package off and it was labeled as "shipment received, Package Acceptance Pending" on 9/22. There have been no updates since then. I messaged the seller about the issue on 9/28 and got no response. I started a missing package investigation on 9/30, but nothing has happened with that.

I'll be filing a claim on the missing package early next week since there had been no resolution to the investigation.

My question is this: what kind of feedback should be left in any? Definitely not positive, but I understand that the missing package is not the seller's fault.

What part should I collect next?

I’ve now collected all the colors of frogs, geodes and rock crystals. I love collecting all the colors of parts. Now I’m not sure which one I should start next.
