Also got recorded message earlier today about air duct cleaning.  Funny how the beginning of the message seems to get distorted so I wonder if they conveniently did that on purpose as to not divulge their (fake) company name.  Also wondering if they found a loophole in the DNC list because they are asking for "donations" rather then a flat fee. Either way they are a pain in the [***] and I'm going to continue screening all calls so as not to waste my name with these low lifes.

Called the number back and got a message that it was not a working number. How can that be as I got a call (didn't answer) from that number yesterday (1/24/12)?

You could try fiking a complaint at donotcall.gov
I got "duct cleaning" calls for "Illinois area" (I live in Wisconsin) with same caller ID, and I just reported.

They use something referred to as spoofing, in which the caller uses false information (phone # and company name) to come up on your caller ID.  That's the reason the callers are so arrogant and obnoxious cuz there's no way to trace them and they no they won't get caught. Try to google spoofing for more info.

1st call came in as air duct cleaning, Reported to the DNC

2nd call was air duct cleaning. Reported to the DNC

With all these spam scam callers the Gov. should be collecting some hefty fines!
