Who called from 4052279380

We got it as well - looks like a bill and could have easily been paid.  
Do not pay anything that looks suspicious - No phone number, only a fax, which is constantly busy, and a YAHOO email address.  If you google the address, you will find that it is a US Post Office.

I got one too. Not sure where to file a complaint

I also submitted it to the Postal Inspector.  They're using a post office address as their own, so that seemed the best place to file a complaint.

Recieved the same fax. The only difference being the number is now "891475" instead of "1475". I emailed them a filthy paragraph at the given email address calling them all kinds of derogatory names and telling them what morons they are. :-) I hate dirt bags.... they should have sand injected under their kneecaps.

I have a little more information to add. I got the same fax this morning with one difference, the number PO box number changed from #1475 to #891475. I've started unsubscribing to the numerous junk faxes we get at the office and this one looked familiar so I looked through the stack I keep for reference and found another one.
This one however was one from Your Yellow Book for a business listing. The fax number was 405-227-9534 and the address was PO Box 891475. Not too hard to figure that one out.
I replied back with an UNSUBSCRIBE fax so they change the name and service and send me another one. When I send an UNSUBSCRIBE fax to this number, I'm going to send about five black pages behind it and waste some of their paper and ink.
