For whatever reason we apparently are not receiving mail scheduled for delivery. Still have an open service number for mail not received on June 09th.


Called to speak with a manager and Cheryl said I can wait on hold or call back to tomorrow. I said I’ll hold, she returned and asked the same again and I said I will hold, she hung up the phone. I called back and she put me on hold again and when she returned she said I can wait, call tomorrow, or leave my number. After 14 min on hold I said why didn’t you ask to take my number As an option when I first called or second or third and during her “you can hold, call back... I said her name 3x which I have on video, she said don’t you yell at me and hung up. I called back 5 more times and she picked up the phone and hung up each time. I called nort Downey and spoke to a supervisor and he said a manager would call and no call. Besides that we get others mail all the time, so who know what mail we are missing.


I know the regular post person is out on leave or vacation, but that doesn't mean a replacement postal server should stop reading numbers and letters for addresses. So why do they leave my mail in my tenants box?.


My husband's medicine has been at the Post Office since last Monday. He needs his medicine . Please for Christ's sake delivery it on this Monday. John Siemann 10225 Foster Road, Downey, CA. 90242 Donna Siemann (562) 803-0301.
