I have had mail in my mailbox for a week. New mail is delivered but the mail in my mail box has been left behind. Not good.


I applied for a passport back in June and gave the clerk 2 certified copies of my birth certificate along with my marriage certificate. I received my passport and one of my birth certificates back. I have been in contact with the US passport office through email as well as phone. I was told by the Chicago office that they never received the other documents and that the post office never sent them to them. I called the Crystal Lake post office to find out where my missing documents where and waited on hold for 41,54 one ever came on the line. I called from another phone and waited on hold for 19.30 minutes. Same outcome. I called a third time and reached someone. I patiently explained my situation and she very rudely said they do not have my documents and that it is not their fault. She said I need to replace my documents at my own expense. I am extremely upset with how I was treated. Obviously, I have certified documents with my personal information lost somewhere and she couldn't even take a minute to show any effort in trying to help me resolve the situation or locate my missing documents.


Flood flyers start on Wednesdays! Why can't we get the food flyers on Tues? Waiting till AFTER the sale has started is a pain in the butt!


On what planet do food flyers start on Wednesdays?
