I live on Marietta drive in fremont. Our regular mailman is EXTREMELY SLOW in delivering mail in this neighborhood. I’ve observed hike being on his phone the majority of the day. The guy is extremely slow when he drives when he walks etc. I’ve witnessed him deliver mail 2 houses down from where I live. After he puts the mail in the mailbox he then sits in his truck for about 5 to 10 minutes and he’s looking at his phone the whole time. THEN he proceeds to deliver mail to my house. Once he’s in front of my house he still sits in his truck another 3, 4 minutes before he gets out. He’s looking at his phone as he’s putting mail in my mailbox. This goes on every single day. I’m getting tired of it. If u add up the time he’s looking at his phone we could be getting our may a few hours earlier every day. Instead of 5, 6, 7, at night. Please do something about this SOON!!!!!

In Irvington district, my mail is not getting picked up from the box in front of my house. This is a ongoing problem. The phone number sends me on a run around with links. The brick and mortar location is not answering their phone.

I was just wondering why twice within a month July/August the post office lobby was not open at 5:40 a.m.
