Another recourse is to go to usps.gov, look for the problems/issues area and send them an email, giving them exact info on your problem. Then from there, this email is reviewed, sent to the Postmaster at the branch (be sure to give them this info) and then the Postmaster at that branch addresses the issue. Then the usps.gov will contact you to see if issue is resolved. They assign it a Case No. and will follow up with you to see if issue resolved. Believe me, the 'clerk/carrier' does NOT want to have to receive this type of "reprimand" twice.
My sister works for PO and she gets so irritated that many of the employees don't care about what type of service they give the customer.
Right now I'm having an issue with my carrier stuffing my mailbox so full that either the packages are tearing when he shoves them in or they tear when I try to pull them out. And I'm talking about bubblewrapped packages and cardboard Priority packages.
Life is never easy, is it?
