- CVCoty VanCuyckAug 7, 20241.0of course the only time i have to send somthing in mail it gets lost
- AHAdam HoweNov 24, 20181.0Always seems miserable and they talk to you as if you were dumb.
- KWKiys WondersDec 21, 20155.0I love this post office!! I ship many packages sometimes daily! Almost all from williamson post office. The other reviewer was right about the boss she does have a bit of an additude but she is always polite . I usually work with one of the counter people instead. Frankly they are amazing!! They do my best to help me ship the cheapest way. Things ship quickly and get where they are going! They even buy suckers out of their own pocket so the little guys can have one (my kids love this)! This store really is a gem!!! Love going here!
- RKRick kMay 3, 20141.0Live in Williamson for 12 years and this has become the worst post office in the entire US. The postmaster directs all the postal employees to constantly search mail going out to locals for extra charges on ALL letters and packages to bring extra revenue into her Williamson post office. I and my neighbors constantly are having our mail held for extra money. This does not even count the letters that we send out don't get to where they are supposed to go 30% of the time and its the Williamson post office. I spoke to the postmaster and she is defiant and won't explain at all the ridiculous tactics she uses. Brought some of the letters she held to another postmaster and they said what she is doing violates postal regulations but they won't help us because as they said she would try to ruin them. AVIOD WILLIAMSON NY POST OFFICE AT ALL TIMES!
