Why would the USPS Mail change/replace entire neighborhood cluster mail boxes WITHOUT providing Advance Notice of when they are going to do this? & NOT provide any instructions on how & where to get a new mail box key?

I would encourage all persons affected by this to direct their complaints to 4 places. Those being the U.S. Postmaster General, directly to President Biden, and to your U.S. Congress persons and your U.S. Senators. This is continuing internal sabotage of the USPS by the US PMG. Appointed by the Previous Guy.

I go out there to find a new mail box system since we are waiting on textbooks for classes that have ALREADY started and assignments due? Yeah, B.S. Poor communications and poor planning by USPS!! https://www.usps.com
