I get an e-mail saying my package is delivered so I check my mailbox....not there. checked couple times today and it says it was delivered early this morning before 9am. I am in downtown (96813) so tried to call and have been on hold for over 40mins.....yeah over 40mins...finally gave up after 60mins. I called around noon so being this hard to reach someone for my mail....when you guys say its delivered but probably in someone else's mailbox? Maybe USPS isn't the best option for shipping and receiving packages.
