Anyone have good luck with the USPS finding their lost auto parts in the system?

And i also found out trying to do anything with the USPS in a phone call is a total waste of your time.
At first i used their national phone number, and going thru threw their prompting, is a pain in the ***.
Then, if you do get thru, the wait time is easily 30 minutes, or maybe more.
But you can have them call you back, which i did.
Then i got the brainy idea of calling the West Sacramento distribution center, from where i got the notification that my package leaked fluid, and all that we have for you is the shipping label.
That facility doesn't like to get phone calls.
It says, "Our message box is full, and cannot take any more phone calls, and try and call back at a later time"
Then when you call back again, you keep getting the same message.
They make it so hard, they wan't you to just give up, and go away.
So it's pretty much, do what ya gotta do, over the internet, and then try and get some satisfaction.
