No one ever pick up the phone. I tried to report mail box problems. There is no voice mail, no email. Called 800 number. Same result. No one ever pick up. Very bad reflection on government workers.


No one ever answers the phone, terrible customer service, yikes!

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.
