Whoever was delivering packages to the town of London (North of Cambridge, WI) on Sunday March 19 was flying through our residential neighborhood at a ridiculous rate of speed. Whoever is in charge of this route needs to SLOW this driver down or a formal complaint will be registered! This is a residential neighborhood so it’s 25mph! This person was driving at a speed much higher, at least 40plus. Please get this person under control! It’s not the first time.


Piss poor service- I had a mail hold until 4/1/2022 and they were scheduled to deliver 4/2. I drove to the Cambridge post office on 4/4 to pickup my held mail but they didn’t have it and the person behind the counter said I would have to pick it up in Fort Atkinson or wait for tomorrow’s delivery. 4/5 delivery comes and nothing from the hold arrived. I called the Cambridge post office and the same person wanted to give me the Fort number to call, I told him no, I expect you to do your job and get me the mail that should have been here on 4/2, I have bills that will get paid late if not delivered today and I hung up. This is BS why do I have to track down my mail that the government is responsible for delivery?
