I have had a package reported to be sitting at the New Castle DE post office for at least the past five days ... but no indication that it has ever been delivered. The tracking number is: EJ907583858US. This package made it all the way to New Castle DE from Miamisburg, Ohio. It was originally shipped Priority Mail Express. That cost me $32 in postage. The final destination for the package is P.O. Box 12006, Wilmington, Delaware. Can anybody help me unravel this mess and find the package or finally get it delivered?

I live in Wynthorpe community. I recently was getting work done to my driveway and the other day I had to back my car infront of neighbors house about 12:30 in afternoon because concrete truck was delivering. I was called by my neighbor and that the carrier said She would not deliver mail because part of my little Kia was infront of mailbox for that brief period of time so she drove by and refuse to deliver. To further add insult was told it was against the law! All my car was blocking was the fact that she would have had to get out of her truck and reach one inch and deliver my neighbor’s mail. What is against the law is when a carrier decides to HOLD MAIL and not deliver because it would require her to get out of her truck and reach a couple inches and put mail in box. It is not like the box was blocked and she couldnt get to it or even see it at all or she would have to walk down the street. This is UNACCEPTABLE and I want to find documentation that would justify this “law”.

I placed an order on 11/29 and the delivery date was 12/4. I didn't receive it I decided (which was WRONG TODO) to wait til Saturday. Still nothing so I called the Vendor they said it was delivered on 12/4 around 3:52pm. I went to the reception desk and there were boxes and mail there but NOT MINE. SO I'M EXTREMELY PISSED OFF. I can't even call you because you're closed I thought you were open til 5pm on Saturday (I'm wrong). So I have to wait an additional 2 more days to talk to you to find out where my order was delivered to. I've never had a problem receiving my mail in the 2 years I've lived here. Clarissa the Supervisor of the Company I placed the order from told me that the mail carrier left it in the mailbox (we don't have a mailbox) & she also said someone signed for it. Now how can someone sign for it if they put it in the mailbox?? Doesn't make any sense to me, none at all. I'd LOVE to KNOW EXACTLY WHAT'S UP!!
