Does the mail run on Monday February 21st, 2022


My mail goes missing 😢


Just want to say kudos to all the employees here in International Falls USPS. Thank you for always being there to serve us during this pandemic. Stay safe and keep on smiling. Good Job Everyone!


I was in the other day to pick up my mail because my mail box I've been getting mail at for 5+ years is all of a sudden 4 inches to low to rec2ive it now. So I thought I would at least be able to come pick it up but I couldn't do that either. She told me I could not receive it until I fixed my mail box. I told her she had all my pay checks anx important documents my attorney needs and that it can't be repaired until I get atleast one paycheck from her and all she says is it's not my problem. I am very sorry for the way I reacted while leaving but I've spoke to many other people around town that have similar stories like mine of her just being rude to everyone. Let's not forget the tax payers that come in there pay her salary. I have had more then 1 bad experience with this women over the lastv5 years or so and I think she needs to be replaced or go through some type of training on how to deal with people. I understand i am. Not the best person to listen to after the incident that I caused which is understandable but I know for a fact there have been other people with similar complaints and feel something needs to be done. Her attitude alone makes it an unpleasant trio every tome.


I have the same problem with her. When are you going to get rid of her?
