bought a home in tarpon springs and still remodeling and not moved in yet......and i got mail for first 2 weeks even tho we havent even forwarded our mail yet. then for over 2 wks my key for comm. p.o. boxes didn't work.....i had to watch for postal worker and finally caught up w/him and he said they changed our box and our key doesn't work.......the us postal worker never notified us they chg. our box w/out notifying us and he said they sent all our mail, mortgage docs etc., back to sender without even notifying us that our key didn't work because they changed our p.o. box.......who does that.....therefore i'll be filing complaint with postmaster general......as we went several times to t.sprgs post office and they never once informed us they chg our box w/out notifying us.
