I just got a call from them. I tried to call back to see what happened, and got a message that my call can't be completed as dialed. I tried again thinking I might have misdialed, and got same message. I agree with everyone else...Do Not Call doesn't work worth a darn. Of course, what Government agency does?
The number called at 11:15 am on Wednesday, 10/23/2012. Did not leave a message however, after checking on the internet other people said they were offering vent cleaning.
