Received great service nationwide and locally when package went missing for a month. I was contacted and notified of its delivery by a case worker in Virginia and our local Postmaster Mark. Thanks guys !!


For the last three months mail from and to me has been delayed at least 10 days! A Valentine envelope mailed from Oregon didn't arrive until 10 full days after it was put in an outgoing mail box. And the stamps one that envelope weren't cancelled. And twice rent checks mailed by my bank to my mobile home park manager were delayed by 10 or more days. Fortunately my manager has not yet charged me a late fee. What is wrong here? Please reply.
