- SNShellee NguyenSep 20, 20264.0Service was great for the post office. Its always busy but the line moved pretty decent. Cannot complain.
- SPsteven parkSep 15, 20261.0These are results for I've filed missing mail 4days ago. Operator called me just about 30min ago. She was so useless and not knowledgable. It was much easier and clear on the web. I've asked her what is usps's procedure and policy in my case, she kept saying "There is nothing I can do". I was asking what is their system to solve this issue. Anyway, I told her this is just waisting time, then she hung up without any comments. I can tell she was pretty old lady by her voice shaking, so I didn't want to be rude. But she is. Show original results
