My mail in my box at my house was NOT picked up today. My incoming mail was delivered to my neighbor over a block away. She kindly sent her son with all our mail on his bike to deliver it to us!! WHY? WHY?WHY? We always discuss Mondays mail- never delivered at a decent time and sometimes not even delivered at all!! Maybe you should not work on Mondays and change to Sunday instead! Please get your acts together!


I wanted to let you know - that my fiancé and I had the best service this morning by Kevin (I didn't get his last name). We came in to apply for our passports for our honeymoon.. and although Kevin was the only one upfront he tried to help us in the mean time helping others. He was so nice, accurate and very helpful.


I posted certified mail from east side PO Feb. 26. My certified mail has not been posting tracking data. It posted Feb. 26 at the accepting facility with note is would be sent to sorting facility. There is no update that the sorting location received the mail. I have called the main STC post office and was told we would look for it and call you today or latest tomorrow (today March 2). I've tried called national customer service. I've left my name and expect them to call me (right?). This was an exceptionally important document going to Fresno, CA. USPS has missed the commitment to get the mail in 3 days and has a ineffective certified mail process. Who will help me?
