The USPS is literally the worst entity/organization I have ever seen. Absolutely low standards because why would they care about customer service. Look at how terrible the ratings are. I have three packages that I have not received in the last three weeks. One package is MIA, one package says it was delivered but it never made it to my mailbox - so I guess the mail person stole it, and one package (This is the worst one yet) I received someone else's package of very important documents including an envelope of money with my package tracking info stuck too it. ABSOLUTELY HORRIBLE SERVICE! I have filed reports and of course no one seems to be able to help. They just don't care because they know everyone still has to use them.
