Dear Sir/Madam, Good day. I am writing to request a second delivery of the package number 9505513482120084545681. It shows that it was delivered failure on March 26. Please deliver again as the receiver is re-opened now. Thank you very much!


This is my favorite USPS location. Friendly, courteous employees and fast service compare to the one in San Lorenzo, and Hayward.
