Very disappointed about the carrier deciding whether mail addressed to a home that was just purchased should be delivered or not because they don't see any activity and ASSume the house is vacant. How is that YOUR decision to make? You're in this tiny neighborhood less than an hour to deliver mail! How do you KNOW about the activity going on here? I had the packages addressed to the new house I'm moving into so that there's 3 less packages to move from the old address! Not that it's your business to ASSume that, either! Just do your job and deliver the packages as addressed, PLEASE! There is junk mail in the mailbox, but packages couldn't be delivered? Did it require more effort you couldn't bring yourself to exert?
Then, there is absolutely no help with resolving where or why these packages that were "forwarded" or labeled as "dead mail:disposed of by post office" could be. The Post master (MIKE) informed me to contact the sender to resolve then just hung up on me after I thanked him for his time. Aside from what the carrier told him, he did not help me find out anything further than what I had already tracked myself online. It was a waste of my time as they are all obviously unproductive and incompetent at doing their job to any satisfactory level. I knew the customer service was going to be terrible based on reviews I read...that's why I was so nice only to be treated like..well...I'll leave it at terrible. Very disappointing!


Does the mail run today July 3rd 2015?


Incompetence and disregard for customer satisfaction by the postmaster carrier are the order of the day for this branch. My carrier lies about deliveries or notices left. Have actually gotten rolled eyes as a response to my concerns from the postmaster. Too bad they're union, they need to be relieved and hire someone who will actually do the job and not just collect a paycheck.
