- MBMonica Buckle6 days ago5.0The Cos Cob post office has the best postmaster, Frank. He goes above and beyond and I am always confident in mailing important packages since they arrive at their destination on time, unlike every other post office.
- ABAlly BernsteinApr 30, 20261.0The service in this post office is horrible. My mother has had issues with this lady, I’ve had issues with this lady, and now my fiancé has had issues. A older Hispanic woman that works at this location shouldn’t be working with the public. She won’t give her name and she doesn’t wear a badge which is what the complaint line told me she should be wearing. She is always either on the phone or talking to other people while she has a customer in front of her. She was the one that did the transaction for me with an international package that was being held up in customs. She said she didn’t have time to look into it (was on her cell phone talking in Spanish) and talking to me at the same time. She told me to leave my info and she would call me. She never did and it’s been over 3 weeks. My fiancé went in to see if she can help and ask for an update and he received the same treatment. I ended up calling the postal service in London and they confirmed that she never put on the label that stated what the package contained and it will be sent back. Where do they find these people
- JBJoseph BarraganMay 3, 20225.0Friendly staff always very helpful!!
- BMBrendan MicikDec 19, 20175.0Gerry and Insook are very helpful. I always have a good experience. I ship most of my products through the Cos Cob USPS.
- CLCynthia LuoDec 26, 20161.0The USPS indicated that the package was delivered to my home on Dec 24, but in actuality it had not been delivered at all. A post office that blatantly lies about deliveries should not be in business.
