My package was delivered to a completely different address, the address is an abandoned home and I don’t see why the carrier would leave it at an abandoned house, still the package is nowhere to be found.

So I had a PKG from Amazon coming in the mail it was already running late and was coming by Friday, well my neighbors have a camera facing our mailboxes and the witnessed the mail carrier toss PKG over the fence and leave . No heads up your PKG is here or hey you mail, nope just tossed and left. Exit stage left. I am utterly disgusted. On top of it I still didn't get the PKG . It was seen being stolen by someone who came into our yard and stole that as well as my neighbors sons shoes. I don't know what can be done but I know it is not me at fault not amazon.. the mail is on 4th Ave and popular who ever delivered on 22. I'm normally very understanding but that is just rediculously in called for
