They have called me some many times in the past 9 months.  I ask them everytime what company they are calling from, and everytime they give me a diferent name.  I have even googles the company name while they were on the phone and told them ithat name does not exsist, and they hang up on me.  I tell them "yes, I am interested, but I will have to call your office in the morning, what is the number?" and they give m a fake number.  I now just tell them that I have called the police and they know who they are, and they hang up on me.  I even went as far as telling them, yes I want the duct cleaning service, but I have to talk to a manager to sort out the details, and they hung up on me.  All calls are coming from India, I am sure.  But I can't figure out what their scm is.  I know for sure it is some kind of scam, but I don't know what!

They called on Nov 3, 2011, didn't leave a message.  Again, this number is not recognized on 411 so I can figured who called and what they want.  Good thing I am away a lot.

Call almost every day.  I am no longer polite with them and they still call.The do not call registry is a joke.  Still get all sorts of unwanted calls.

An air horn from sports tore or boating store works wonders.  They do not abide to the do not call list.  So a large blast on the air horn will send a message.

They have called me many times as well. I've tried the hang up approch, the rude approch, and everytime I try the ~I would like to know more about who they actually are~, they hang up on me. I am hoping they call agin so I can actually have an air duct cleaning service company come to my house........ I'm sure it will get interesting from there. Maybe then I can find out who gave them the tip and help bury these goof balls.

If anyone gets the company name post it.  I'll show up to the door, summons in hand and serve them personally.
