I'm too expert at this

USPS was once a client of mine-I know too much about what goes on there and I also know that good people will say anything on a forum that is unable to verify anything that's said. Ok. got that out of the way.
I'm constantly testing my former client to see what they do.
Indeed. I have had almost everything imaginable that's bad, happen to my postal transactions. You might say I could write a book.
About your exact situation.
1) Insurance helps but is NO guarantee that you see the claim honored. If your claim is honored, it will only be after a HUGE battle with USPS, entailing investigations that sometimes take as long as a year.
2) Delivery confirmation is just that- the carrier logs the delivery into the system when they DROP the package into your mailbox or at your doorstep. It is NOT a tracking number.
3) USPS is not the most reliable carrier- it simply used to be the cheapest. For reliable transport, you must use UPS or an of the expediters (FEDEX , DHL etc)
4) I ALWAYS :
A- get a witness to merch being packaged and sealed
B- Photograph the contents next to the package with the shipping label in clear view
C- Photograph the package once postage has been applied with the receipt in clear view. * Because I use the APC kiosk so much , this part is a must do.
After the postage has been applied I try to get the teller to postmark my receipt .
D On expensive shipments, I keep all proof together in one place with a staple.
In all fairness, 95% of USPS handled packages get to their destinations as scheduled- safe and sound.
In more cases than not, undelivered package claims are the result of fraud on either the part of the sender or the recipient - not of the carrier.
The incidence of fraudulent mail claims rises exponentially with a downturn in the economy.
So- I do feel sorry for you, because I know it really does happen that real losses do occur from time to time. Next time, just follow my due diligence guidelines and it will be easier to prove your case to USPS and the community at large. And remember, USPS is only just a bit cheaper that premium carriers.
The last couple of days have sucked. Long story short....I had a couple of packages inbound. I checked the delivery confirmation number and it said the pkg had been delivered. The problem is that I didn't get the package. Stupid me didn't request insurance. I call the PO and eventually meet with my mail carrier at the box. The mail carrier told me that she put the packages in the box. I trust her, better yet, her supervisor trusts her (I did cover my bases and call him). I call the cops and have a converstion with a couple of officers. I find it best to keep them in the loop on this even though they have no jurisdiction. I am filing the postal paperwork right now.
Is there anything I you guys know of that I can do.
For the record, the knives lost were a Ti ZDP Leek and a Blk/Blk JYDII.... argh where the heck am I going to find another ZDP Leek.
Anyway, if you have any help....Please Help Me
