- JDJellyfish Daydreams6 days ago1.0For the 6 years I have lived in Key Largo, this post office still cannot offer a decent service. This time, I sent a package that has disappeared. Tried calling multiple times, but nobody answers the phone. Took time off of work to visit the post office and find out what might have happened, and I was rudely told “we don’t answer phones here”, and I asked about my package to see if it was there, and I was told “nah, it’s probably in Miami or Opalocka”. Didn’t care, didn’t get my tracking info, just rudely dismissed me and walked into the back. Save your time and ship elsewhere. This whole post office needs an overhaul of workers because they just can’t seem to hire professional or competent workers!
- ASAshley SevillaMay 13, 20261.0Every time I call to check package status and do a pickup at the location. They always say that you can come in and pick up your package. Yet when you get there they don’t let you pick up always give some different excuse. And the workers act like they couldn’t even be bothered to try an help. Just terrible
- LCLucy CMar 31, 20261.0Employees take it upon them selves to send my express package 📦 by nail mail after I paid and left a tip the office just pockets the additional amount instead of putting towards sending my mail as requested very disappointed and inconveniened!
- DWDesiree WeickJan 31, 20261.0Very poor mail service
- MMMelani MesaJan 28, 20261.0En menos de una semana he tenido una pésima experiencia con la entrega de mis paquetes , no sé si será un nuevo repartidor o lo que esté pasando pero ya van dos ocaciones donde me entregan el paquete roto o sin ningún artículo , hace unos días lo dejaron a mitad del patio porque no cabía en el buzón en lugar de dejarlo en la puerta , estaba totalmente destruido y se perdió una de las 2 sandalias que venían dentro y el otro paquete lo dejaron abierto y sin nada dentro del buzón . Quien responde por eso ? Porque vas a la oficina y no están los artículos
