United States Postal Service [USPS] review: received mail at 4:50 pm

Been living in same neighborhood for over 42 years. Since we received new mail post master at 60069 we are getting mail later and later in the day. We are unincorporated and I believe they just do not care about us since we do not have a village to complain for us. There is no excuse for getting mail at 4:50 pm. What happens is they take care of the offices first then the corporated area the after they are through they deliver our mail after the postmen have delivered there routes. We are an after thought. This happens when our regular carrier is off and the replacement deliveres the mail. The post master Katie tried to lie to me about what happens but after living here over 40 years I know when I am being lied to. Really bad service and there is no need to lie.
