I have made several complaints over the years and get no where. Our mail is constantly delivered to the wrong address. Further I will be contacting fedex who now ships with USPS on weekends, now have 2 large packages missing.


Hello. The person who brings our messages and everything that belongs to us from shipping something late and often and sometimes in many days of work does not come and I am waiting and not Batty and sometimes a lot comes at 3 pm I wish the officials to appreciate this note and thank you very much


I've always had a great experience at the Post Office in Windsor. Love all the employees. Thank you.


I have tried to call the phone number listed above and it's not a working number.


My mail is all soggy from the rain. The mail boxes at the corner of Gabrielle drive and Amie Dr. need seals. Important mails and expensive journals are being ruined by the water.


Windsor has the MOST uncooperative and lazy employees. Windsor plowed the wrong side of street. I cleaned a path to the mailbox and haven't received any mail since the snow started. I work all day and don't get home before your closed. How can I get my mail cause I need it. there are checks bills and a package that I need to get from you. I can't shovel the entire side of my street. But I'm sure a the mail lady can walk 3 steps to put my mail in the box. I just talked to her and she said
" Don't Get Me Started" I want a manager to call me ASAP. 4437912245


phone busy all afternoon!!


I just tired calling and received a busy signal. Then I saw your comment, so I won't bother calling and just go in! Thanks!
