> I had the right package. It just wasn't mine. It wasn't addressed to me.

I think this assessment was the root of your problem. This wasn't what happened. What happened was two separate things and the mistake was tying them together.

You didn't get your package they claimed to have delivered. Full stop. Deal with that problem.

Second, you received a package addressed to someone else. Deal with that separately.

If you need the package soon, that’s not great.
