I bought a postcard on
ebay from Latvia on Feb. 6. It left Latvia and arrived in LA on Feb. 12th and hasn't moved since. Is there a way to light a fire under ISC, USPS? I tried to reach Customer Service at USPS but the response was it wasn't I guess delayed long enough. At what point does it get to be too long? The item is a small stiff envelope with one postcard inside and maybe the packing slip. Thanks.
