USPS United States Postal Service Insurance scam Nationwide

USPS postal insurance is a scam. They don't have a written out policy detailing what is required if you end up needing to file a claim for lost or stolen shipment. They appear to never intend paying a claim. On their web site it says you are buying declared coverage. I declared a value when I bough the extra insurance. Their agent saw what I was shipping and did not tell me it would not be covered. She sold me the coverage. When the shipment was lost or stolen they denied the clam. They want to know what I paid for it in 2008. and they want a receipt for that purchase. Item still has $1,200 price tag on it from when I purchased it. This happen to be a 1 carat diamond ring. When I bough it, I bought three of them. When they denied the $1,200.00 value I had one of the other rings appraised by a local jeweler. It appraised for $1,900.00. They don't accept that. This item was shipped in a small flat rate box with $1,200 extra insurance. Both the flat rate box and the insurance require scanning every time it changes stations. It was lost in los Angeles for 8 days. then it went to Rondo Beach. last scan when sent out for delivery. During the 17 days it was in transit I filed 4 cases trying to find and keep track of its status. I never got a reply to three of those cases.  The USPS does not care about you. They change and add new rules to suit their needs. Scam you and the boat you came in on. BUY PRIVATE INSURANCE. Do not use USPS for anything.
