Call came from Steam Wonder. Returned call, the number wasn't accepting calls at that time. Going to try about 2 a.m. and see if they're available.

Try calling 586 530-2443.  I got an illegal robocall on Saturday, this guy called me back on Sunday. This number ties in to Quality Control Premium Air Duct Service and there are pages of complaints against that number.

Seems that complaining, asking to be removed, etc. has no effect.  The guy appears to be a real piece of work.  Complaints to donotcall.gov aren't working.  Call your Congressman. And whatever you do, don't let him into your house.
