I have been trying to have my address changed since April. Each time I go to the post office, I'm told something different that I have to do. Then, I was told unless my Identification is scanned, my request will never go through. Now it's June 29th and I'm being told that further identification is needed. Which means I will have to wait for another 2 weeks just to see if my change of address request will be granted. 4 months to change your address is a little bit ridiculous.

As I read some of the negative the reviews, I wondered to myself. I have used this post office for 26 years for all my services I needed. I have found my overall experience to be very good. I have had mail lost or delayed, long wait lines, and at times what seemed like workers doing the best they could with what they have that day. Because, I'm in the customer service related business, giving GRACE! Great job for the seen and unseen staff working at this location.

I came here in December to get my daughter her first passport and the lady who helped us could not have been more helpful or kind. I came here today and had the opposite experience when renewing mine. I was told to sit in the chairs, then they asked if I had an appointment, which I did not and that I was just there for a renewal. They told me to stand in line. I had my documents already filled out. Went to the counter and then she sent me elsewhere to get my photo taken. Then back to the counter but apparently it was the wrong one so the passport lady had to keep coming back ("but if you went here, I could have done this"). You know, it's just not clear what is to be done in there- it would be nicer if the people working there could give better directions and be helpful. Not act like I was a complete bother and should have known what do to - because well, clearly I didn't. And I guarantee most people are not sure either especially if they have not been there for passport services. So please, be kinder and explain better to the next customers what they are to do to expedite their needs.

Worst customer service ever. Had a package go missing, they found it, got like three different calls, one saying it was at the office to pickup, another saying it was out for delivery, and then another saying it was at the post office all in the same hour. I wasted my time going to the office because I didn't see anyone downstairs like they said, and was met with the rudest lady ever. Extremely condescending despite the mixup being their miscommunication, and basically just told me the most useless information ever. I still don't have the package! All of the employees here are useless and rude. The supervisor is nice at least.
