I live in a place with the rows of boxes for all the tenants in one central location.  I have a book stuck in my mailbox.  The problem is that the carrier's side is about an inch wider than my side is.  I've tried every angle, even bending the book...it must be a hardback, because it is an no-go.  I called the post office once and they assured me that the carrier would be alerted and would fix the problem.  I went out of town for a couple of days and when I come back...the book is still in the box, not in the large parcel area.  GRRR. 

What should I do?  I'm thinking of leaving a post-it note taped to the carrier's side of the box tomorrow.  Surely he (or she) has noticed that this same package has been left two times while other mail has been removed. 

sure, try the note to the carrier, I'm sure he/she isn't aware of it being stuck-most carriers don't pay a bit of attention to what's already in the box, you'd be surprised at how many people let mail accumulate in the box for a week or even longer. Carriers are conditioned not to even notice other mail in the box. 

sounds like the message didn't get to the carrier. Your best bet when making complaints is to use the website. That generates a paper trail. The Supervisor will get an email early in the morning and they can print out something for the carrier. They have just a few days to answer the complaint or their boss is on them for having eCC (electronic Customer Care) cases that are old. the district runs a report every day to check that the eCC cases are being cleared. 

If you call the office, many times nothing gets done, there is no paper trail. you might have called at a very busy time and the supervisor had to go back to do a report or something and your call slipped his mind, that's why the computer is the way to go, they have a paper trail right in front of them, they can deal with it during an unbusy time, and they must deal with it or deal with their boss.
