- ABAshley BurkelSep 22, 20265.0Best customer service I’ve ever received at a UPS store!
- BNBuck NekkedSep 10, 20265.0The lady at store #3890 was incredibly helpful and nice.
- SWSharon WSep 8, 20264.0I’ve dropped off Amazon return packages here several times, and I’ve never had any problems. The line can be long sometimes because it’s a busy location. I also have a P.O. Box here, and I’ve never had any issues receiving my mail. My only complaint is about getting your passport renewed. If you need a passport photo, I highly recommend getting it taken somewhere else—preferably at a place that specializes in professional passport photos. 😂 The ugly passport photo they took of me is going to follow me around for the next 10 years! I’m honestly embarrassed to travel with it. LOL. Other than that, my passport renewal process went very smoothly.
- EMEfesio 2:20 MSep 3, 20265.0Muy buen servicio
- KKKevin KellyAug 18, 20261.0I've had multiple problems here. The latest example is then refusing to ship an Amazon return because 41 lb is "too heavy to ship."
