- AAAlanJul 3, 20261.0This place is the worst post office and this is saying a lot as the entire organization is a disgrace. Total distain for the public in general and rude incompetent staff. Front desk and postmaster are a joke. In any other industry these fools would have washed out years ago. Go ahead and use any other service if possible. Your package has a 10-20% chance of being received on either end of it goes through this post.
- SSSamantha SanfordJun 8, 20261.0I dropped off packages in the back because I have many and they lost multiple packages!!! I lost hundreds of dollars on each package and so did my customers. Plus one of my customers who loves on the other side of the country is getting a message saying their package was picked up in Dennis ma?!?! Never ever again will I use thos awful post office. I understand mistakes but multiple in the same place at the same time for the same person?!?! Outrageous. Who's going to pay for these damages because it doesn't even show that it made it to the post office because thry never scanned it in!!!!! Im so upset and disappointed with this post office and usps in general. Usps lost 2 of the most expensive items ive ever purchased 2 weeks ago too?! Like why and how does this company still exhist?!
- PGPatricia GarciaMay 17, 20263.0The food is consistently what you'd expect from a McDonald's, and the service is usually fast and friendly. However, I have encountered some issues with the cleanliness during my visits, which could definitely use more attention. Overall, it's a decent spot for a quick bite.
- KTKevin TrippApr 8, 20265.0The Dennis Post office from Matthew on Down had a Very Friendly , Courteous Helpful , Knowledgeable Staff😉It's a Pleasure Dealing with these Very Friendly People that make You feel like Family. 😉👍🕊️🇺🇲Keep up the Great Job Everyone There, Thank You, Kevin Tripp..👍😉🕊️🇺🇲🇺🇲
- JOJon OhmanDec 8, 20192.0On Monday December 2, I tried to send a package to Pat Kerchen, who lives at 47 Fullam circle Allenstown, NH. 03275. I checked the current location of the package with my tracking number and for some reason the package went to Jamaica, New York. I don’t know why the package went west to New York instead of north to New Hampshire. What kind of service is this. A package being sent to New Hampshire shouldn’t have to go to New York. Whoever is sending the package send it in the right direction.
