No mail delivery on Clover Valley Road on 12/06/2017.


The postman who delivers in the South County of GV drives way to fast. He often drives down our private drive where the speed limit is 10mph. He barrels down the road exceeding this speed and almost hit my dog today. I have also had mail for neighbors in my mailbox on numerous occasions.


I am obviously wasting my money on delivery fees because my parcels are not delivered on time. Instead, I receive a pink notice to collect my parcel from the post office. This is mail carrier dependent and the person delivering mail this month doesn't attempt to deliver parcels. There is a notice in my mail box that parcels can be placed in the pump house so having dogs is no excuse for not attempting delivery. We live on property and the pump house is at the start of our drive. We want our usual driver back as the current one obviously has no critcal thinking or customer service skills.


Why can everyone EXCEPT the grass valley post office deliver a package. When you pay for second day shipping you should get your package in two days. Not a notice that your package is 20 min away from you, come and get it. And when you get there you are told it's still on the carrier, even though you stopped and asked the carrier and she never even loaded it... So you get to do several unnecessary trips to get your package that anyone else would have had to you days sooner. This is the sixth time...


For w hile other people's mail has been in my box.Lately it has been a lot worse.Yesterday my mail was on top of the box.The situation worsens as the weeks go by.Very poor and unusual for USPS.
