- TPTariq PatanamSep 4, 20265.0Staff were super helpful. Paul, Jasmine and Pamela went above and beyond
- SDSpace DoggyAug 18, 20262.0Beautiful building but they have a SINGULAR worker. Not their fault though its the states for not providing them help.
- MAMolly AustinJun 11, 20262.0The rudest customer service I have ever experienced at a post office. They act like customers are an inconvenience. Will not be returning unless I absolutely have to.
- DMD' MMay 6, 20261.0Mishandled mail. Incredibly rude staff
- PGPaulo Guzmán GuillénMay 1, 20261.0**Unprofessional staff and zero management oversight** I’ve had two terrible experiences at this location and will not be coming back. My first visit was about a month ago. I arrived at 5:02 PM and the doors were wide open with the office looking completely empty and unsupervised. Since it was open, I walked in, yet the clerk treated me with total hostility, complaining that he "had to leave at 5:00." If the branch is closed, the doors should be locked; you cannot leave an office open and unattended, then be rude to customers for entering. Today, May 1st, was even worse. I was trying to transfer funds on my phone to complete a payment, and the clerk—Paul, according to his nametag—started yelling at me. He demanded my "full attention" in a very aggressive and disrespectful tone, making it impossible for me to concentrate on my banking. It eventually turned into a shouting match because of his refusal to be patient or professional. When I asked for his name, he refused to give it to me. It is deeply concerning that an employee feels comfortable screaming at customers and withholding his identity. Where is the manager? This employee clearly works without any supervision and has no regard for basic customer service. Truly a disappointing and stressful experience. Avoid this place at all costs.
