Few years ago, I bought a set of Magnacore plug leads on Ebay for a great price, new. Asked the vendor where they were, eventually. He provided shipping details, including a signature that wasn't me.

About a week later, knock on my door in the evening. It had been mis-delivered to one of my neighbors, who opened it before realizing that it wasn't for her and got scared about "interfering with the mail" - she sat on it until her husband came back from out-of-town and took care of it.

Heck, I opened an Amazon package a few months ago, thought "Cowboy paperback? WTF?", looked at the address label and went and gave it to the person it was addressed to.

I'd involve USPS first, then the credit card company. Just the fact you're willing to talk to the Postmaster should demonstrate that something needs to be addressed.
