Sent AOS by Priority Mail, but got "Refused" information from USPS

[Reneehao 0]

I sent my parents' AOS package on May 29 by Priority Mail with Delivery Confirmation, but from USPS tracking system:

Detailed Results:

Refused, May 31, 2009, 11:34 am, CHICAGO, IL 60680

Delivered, May 31, 2009, 11:34 am, CHICAGO, IL 60680

Arrival at Unit, May 31, 2009, 11:02 am, CHICAGO, IL 60680

Processed through Sort Facility, May 30, 2009, 1:30 pm, ELK GROVE VILLAGE, IL 60007

I went postal office again, they told me there was an typing error. My mail was in "Firm Book", which means there were many application mails were deliveried at the same time, no way to refuse my package.

Is there anyone here has the same information as mine?

USPA is saying:

Your item was refused by the addressee at 11:34 AM on May 31, 2009 in CHICAGO, IL 60680 and is being returned to the sender. Information, if available, is updated periodically throughout the day. Please check again later.

Untill now, I have got any returned mail yet. What do you think?

Thanks,

Common notice on USPS notification system, there is no one to sign for packages at PO BOX.

It gets delivered anyway.

You mean even "Refused", still delivered? I came from China. How about you?

Same as my situation. I came from China and my husband is an American.

Now my parents' checks were cashed by USCIS.
