United States Postal Service USPS Yet another insurance claim with USPS perpetrating constructive fraud St. Louis, Mo. Nationwide

 Package was insured with USPS for $250. Contents destroyed, with an estimated replacement value of $271.

Claim filed and USPS sent a check for $50., with letter stating "Your claim has been approved, however it has been paid at a lesser amount than requested." (No reason??). It goes on to say, "If you wish to appeal, send to the Claim Appeals Office in St. Louis, Mo." All of the paperwork and documentation was sent to the appeals office along with extensive photos of damage, original packaging, all receipts including insurance, and formal written estimate from replacement service center....all mailed on May 25, 2014. It is now August 15, 2014, and I have had no relpy. On July 22, 2014, I mailed a followup letter to complain to the USPS Consumer Advocates Office in Washington, D.C., and I have heard nothing from them.  With all of this in consideration, one can only conclude that this USPS is totally dysfunctional.  What will it take to get the attention of these people? Is there a class action lawsuit I can join. Can anyone out there advise?  ...... VICTIM
