What needs to be done in order to get mailboxes replaced on Birchview Drive in Clinton, Maryland. The mailboxes are "rusting" which are making them weak. The mailboxes are wobbly and makes the development look terrible.


The Mail Service Stinks


I called this location to find out why my Priority Mail package was not delivered on the day it was supposed to, and when it would be redelivered. Only one delivery attempt was made on 12/22/2017 which is two days after it was supposed to be delivered. I was told I had to come pick it up. They would not redeliver it. The business where the package was being sent was closed on Friday. Common sense would tell them to deliver it another day.


Waited on package to be delivered. Checked the tracking number, stated was delivered. Never received my package. Tired of the constant mistakes with our mail.


Called Clinton USPS to locate a package that was taken there to be deliverd to Tx needless to say as of right now do not know where package is, tracking says in transit. Tried to talk to the manager Robert rudest man kept to ask about clerk talking over me would not let me explain or get a word in edgewise when I raised my voice over his said I was yelling at him and hung up on me


Per documentation a package from FedEx a package was delivered to your location and you were to deliver it to me. Well as of this date I have not received it. The FedEx Tracking number is 728386445480 and the package is coming from Women Within. The date of delivery was 4/07/2017. I think the delivery was left at another 6913 address in my development. There's one on Northgate Parkway; one on Groveton and my address 6913 Crafton Lane. Any help you can render to help me find my package will be greatly appreciated! Thank You.


Very dissatisfied. Never have I had a package go missing from any other mail or package deliverer. Only this post office seems to have problems delivering my packages. First my home address, then my office address both in Clinton. A disgrace, maybe its time we went over the local person in charges head to get things straightened out.


I have never had so many problems in my life with a post office. This is the 3rd package i haven't received. I'm going to have my mail sent somewhere else. I put big numbers on my mailbox so it's obvious but the post office still gets it wrong. How is that even possible?


We are standing in line 13!deep and two postal workers walk away from the counter now for nearly 15 minutes. This is a Saturday morning and these people should be doing their job as quickly as possible. If u had option I would upload a picture!


conversations on phone say one thing and website says something else.
