Does anybody know a phone number to contact someone at USPS,I just received a package that had been damaged in shipping and some of the contents are missing,they taped it back up and put a note on it that they are sorry,but I need what is missing from that box.I've been on their phone support line for 1/2 an hour trying to get a hold of a person,when I finally did,she hung up on me after I told her what I needed.
