Been waiting over a month for a piece of mail. I call and the mailman tells me that I need to take responsibility because if he does not know the name he will not leave in mailbox, however has left packages before that didn't belong here and comes back days later asking for it back.

I wish I could give 0 star review. This post office is the absolute worst. My packages never get delivered there is always an issue and I end up having to go down to the post office. My mailbox is always left open getting my mail soaked every time it rains. The post office absolutely never answers the phone. Every time I have to go down there I get an attitude. I understand they are short staffed but this has been going on for way too long and nothing is being done about it.

So first I look up the phone number on Google. They give me a one 800 number that refuses to let me speak to someone. I called it four times and went through dozens of prompts and none of them pertain to my issue. Then I find the actual phone number listed a little further down for our post office in Winthrop Maine. So I called that Number and it says that it is disconnected. It is no wonder why they get such a lousy rating. My issue is that I can almost tell that it’s going to rain by the delivery person. Every time the mailbox is left open it rains in my mail gets soaked. It has barely Rained here for almost a month and the mailbox was never left open but of course today it was left open and half of the mail was soaked. I guess the driver didn’t care about the mail he was more concerned about his arm getting wet to close the door on the box.

The mailman NEVER delivers my packages. Instead, he says that he attempted delivery and requires me to pick it up at the post office. I am disabled and do not drive. It is less than 1/2 mile from the mailbox on the main road to our home. Therefore, it is his duty to deliver. We have complained to the post office several times , but the carrier continues this behavior.
