Please tell me why one of your mail carriers thought that our house was vacant and stopped delivering our mail for over a week now without notifying us. I am not please by this and it has screwed up our mail/bills being sent to us. Our house has a mailbox set up and there is my boyfriend’s truck parked there day in and day out. Thank you for causing us so much trouble :(

I have lived in Cahokia my entire life and have never been a fan of this post office. There have been some of the rudest, laziest workers I have ever come in contact with. There is one worker, however, that has been the best I have ever seen there. Mary Agnes has been at this location the last few months and I am ecstatic when i see her behind the counter. She is polite and goes out of her way to help every time I see her. Please make note of the amazing job that she has been doing. Thank you.
