And one more thing, i tried calling them for half a day, but nobody answers their phone at all, never even before, because i wanted to call them to report this problem, but USPS has the worst service because they never answers their phone.

This is already the 2nd time that happen to me, that they said they delivered my package, but never did receive the package, i have another one that they said they delivered yesterday, hopefully one of them can read this and expedite my package, this is my tracking number 9405511899561888136393, it shows delivered 12/26/2014, but i never receive it. This is already the 2nd time that they did not deliver my package. Please expedite or check with your mailman where did he deliver this package, he might had delivered it, but not to the right address. Thank you.

This Post office is horrible for
passport application. Cindy is the worst worker I have ever dealt with at any
establishment.She
was very rude, demanding, and arrogant. Everything needs to follow her own rule.
It's more like "If you want your passport filed through here, my way or high
way" attitude. There aren't much place accept passport on Saturday, so I have
to suck it.She
asked us to copy our ID at a place 3~4 miles away from the post office, while
they do have a copy machine there. This is not my first time to apply for
passport, other post offices need to see the original ID and make the copy on
site to insure the ID is legit, while Cindy insist that we have to make the ID
copy anywhere else, but not post office. I was nicely asking her if we can pay
for the photo copy at the post office to make things easier and quicker, but she
still insist that she doesn't want to do it. I have no clue why she would
refuse such a thing and make us drive 3~4 mile back and forth just for a photo
copy.Well...
We made the trip because we have to do it on that day for personal reasons, and
came back to the post office. Then she still need to see our ID to compare
with the photo copy...... Again, why wouldn't her just verify the ID, make the
copy right in the post office at the first place, and make everything nice and
quick? I really don't understand. Why is so hard to make a photo copy with
the copy machine behind you uh? Cindy.After
this all pointless wasting time photo copy thing, she was still rude on other
things. For example, she insist to punch holes on things we don't want her to.
She insist not to include supporting document while we believe it's necessary to
make our case smoother. Everything is her way or high way. I really dislike
her. She was extremely rude, demanding, and arrogant. So frustrating!!Again,
her name is Cindy! Cindy! Cindy! Don't come here for passport because you will
need to deal with her. Ah, I remember when I asked where to apply for passport
to another officer, she was yelling loud and arrogant behind the counter and
said "You want your passport, you come to me." So I think she is the sole
person who deal with passport at this location.Give
yourself a break, Go to Rancho Cucamonga Post Office on Arrow Hwy/Route if you
can do it during the weekday, they are MUCH better! Service are way better,
positive attitude, detail, respectful, and they make the photo copy for
you.If
you are only free on Saturday like my wife does, search for other place instead
of this place.DON'T
COME TO THIS POST OFFICE on HOLT for Passport!!! CINDY IS THE WORST!DON'T
