This post office is very incompetent. Our community post box has a broken key in it and we have not had any mail delivery for almost 2 weeks. Went to talk to the supervisor at Grantville PO and was told he was too busy. Out going mail has been left in the box through entire time. There excuse is that it takes time. Should only take a day or to to replace the lock. Who will be responsible for late charges or for the cancelation of insurances when the payments are stuck in the outgoing box. FIX IT


Dropped off a package and asked for postage on Aug 3 2021. Was "served" by a young dark haired young woman wearing glasses at about 3:15. She spoke in a very rapid, clipped manner. Difficult to understand. It was very exasperating. I have excellent hearing. Got to practice patience. She was made aware that I was not understanding her well yet she didn't change to help the understanding. Disrespectful. Should be replaced by a machine.


The mail boxes at mission gorge place were locked on sunday 10/18


Status on 5/23 said delivered at 16:00. Went to check the mail at 18:00 and it was not there. It might have been dropped in the incorrect box.
