Complaint Review: USPS Post Office Severn MD 21144

In Nov 2014 I shipped a valuble used auto part thru the 21144 USPS location and paid for $300. in what they call "Insurance". What they don't tell you is that if you have a claim for damage, you must file "Online" and all information must be downloaded as a specific format. They also do not tell you it will take MONTHS for the process. Filed a claim and got a reject letter. Spent hours of time taking pictures and copying documents. Sent back an appeal on paper in Jan 2015 and even paid for a confirmation receipt. Here it is Feb 2015 and still nothing. Tried to talk to "Postmaster"  ( The Princess) Banks there on Feb 18, 2015 and she would not talk to me in person. Wanted to call me. When I relayed to "HER" that I wanted a in person meeting, I was told to come back "Tomorrow". Her crony workers could not remembrr her last name when asked for even tho they work for HER.  What a bunch of S_IT these people are. Don't waste your money on "Insurance" at the USPS  anywhere. Flush it down the toilot - at least you can enjoy watching it go around in circles before it disappears. The Princess should be fired.
