I would like to report the possible intruded our mail box station on 2339 Monroe Street for all apartment units today, 27 June 2020 at 1:59 PM.. I went to check our mail and the whole front doors of mail station are wide open. Please notify and send someone to check it out. I am afraid that our mails have been stolen... I am living at unit #11.


Hi, My order seems to have delivered as per the USPS tracking information. However, I do not see any key placed in my mailbox to be able to pick my parcel from the parcel locker. I have been trying to reach 408-748-9868 number constantly since morning. I spoke to the person once earlier today - he said he would be following up on it. And now, nobody seems to be taking the call. I have been on this since the last 4 days and nothing seems to be moving. Please help.
