I don’t understand why I get emails everyday from you telling me what is going to be delivered and I don’t get it delivered the same day. I have in the past talked to the post master about this and nothing fixed. Also my mail carrier does a horrible job. Bad attitude and she constantly complains about her job and hours she has to work. I have heard her complain on my outside camera about me as well. She should find a new job.


I called the post master in Isanti several times about a situation that they created last January/December. Very hard to get past the guy who works there in the morning hours. He is very patronizing and antagonistic. When I finally was able to get past him to someone else to relay my message, the head post master would not contact me back. My mail was with held for two solid weeks. I did not get my Christmas check. If I was a person who lives from pay check to paycheck and has small children, it would have been devastating. Finally after two weeks I got 26 pieces of mail in one day including my Christmas check. I called and complained before this time; of course the guy who works there lied to me and said my mail was not with held. Liar, Liar pants on fire!!! You are such a deceiver. Can I help you, he says, REALLY! how about delivering my mail and quit lying to me. Than I get this notice in my mailbox. You need to remove the snow in front of your mailbox REALLY! There are ten mail boxes together on Whiskey Road North West and I am the one who gets their mail stolen for two weeks, you lazy liars. You are all a bunch of self serving employees who do not care who you hurt. If you try this hurtful trick on me again this coming winter I will file a Federal complaint against you for stealing mail. Don't think you own the post office and can do your sanctions on any one. You are not exempt from federal prosecution.


i live at 26355 hwy 65 NE on several times i have gone out to get my mail and i found it on the ground so who ever is the mail person they do not know how to shut the mail box i had some very important mail it was all the to the end of my yard in the ditch so i am not very pleased today march 17 i hope it does not happen again thank you
