My mail man broke the door on my mail box. Do you repair or replace them? I am now holding it up with duck tape.


Mail is always delivered in a timely manner. Packages are treated with care. PO staff is helpful and responsive to requests made to carriers and associates.


I'm recieving mail with the last name wheelock that is not my last name and would appreciate not receiving any. Thank you Melissa Buser


Write: "Return to sender. Not at this address" on the letter, and put it back in your mailbox for the letter carrier with the flag up. They'll take care of the rest. If you can cross out any barcodes that the post office printed on the envelope. Hope this helps.
