- TAT ASep 4, 20261.0I’ve had ongoing issues with the mail service at the O’Fallon, Missouri post office on Church Street. There seems to be very little consistency with mail delivery. Mail is frequently delivered to the wrong houses, which is frustrating and creates unnecessary problems for residents. Another concern is the attitude of some of the carriers while they are out in the neighborhood. Their interactions and overall demeanor can come across as unfriendly or unprofessional. I’ve also noticed carriers driving through the neighborhood at what seems to be an excessive speed, which is concerning given the number of pedestrians, children, and other vehicles in residential areas. I understand that postal carriers have a demanding job, but accuracy, professionalism, and safety should still be priorities. I hope the post office takes these concerns seriously and works toward providing more consistent and reliable service to the residents of O’Fallon.
- AVAnthony VanArsdaleSep 2, 20261.0What's the point in paying for 3-day shipping if it takes 2 days just for you to accept the package and then you don't send it for another 4 days...last I checked that makes 6 days, what did I pay for?..🤔
- PMPatrick McMahonSep 1, 20261.0Every year I miss weddings, birthday cards and tax info. This time it's a missing passport with tracking number. 55 years old. 4 states several cities and towns and I've never had this much trouble
