There is no way to reach the official at the Northfield IL post office. I have tried four different phone numbers and have no answer to my question. I have personally visited the post office and found the post master was not there that day. i am getting no mail and a note was found in my box to NOT deliver mail as it was to be forwarded. That status was changed last week.


I cannot tell you how annoying it is to go into the northfield, IL post office and have to wait in line because you have ONE cashier on duty. AND SHE COULD T BE SLOWER. Please put someone on during busy afternoon hours.
