I got the recording of "Diane" cheerfully offering carpet cleaning. Pressed "1" and got a man who said "carpet care" or something, and when I told him I was on the do-not-call list, he hung up on me. I registered a complaint at donotcall.gov and here's what that site says after you hit "submit" on the complaint form: "Do not call complaints will be entered into a secure online database available to civil and criminal law enforcement agencies. While the FTC does not resolve individual consumer problems, your complaint will help the agency investigate the company, and could lead to law enforcement action." So, no promises of action, but the more complaints the better I would guess.
