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.

i know what the heck.....no answer, I am on sick leave so getting no sleep...
my husband always askng me too who calling....

They have called me every day this week between 3:50 and 4:05 p.m.   Same thing, when we pick up there's dead air.    I call back and get a recording that it's going to voice mail then the voice mail is set up to say it's full.I, too will find their company information and report them.  I am also on the Do Not Call list, it has stopped about 95% of the scammers but these guys somehow get through.What do they possibly get out of calling and saying nothing?  They certainly don't drum up business???

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!

My husband is very ill, we aren't getting much rest and these idiots keep calling but never speak to us.

These "Duct Cleaners" have been calling me every couple of days for several weeks. I started out very calm and polite. Told them my ducts were just cleaned - they hung up. Told them Asked to be taken off of their call list - they hung up. I'm sure the stories are all the same. Decided to tell them that I am busy at the moment but would like to call them back to discuss - asking them for a company name and phone number - which of course they won't give... they would prefer to call back. They told me the name of the company is "Duct Cleaning Company". haha. Now they swear at me. Good grief.The hang ups were annoying... the filthy language unacceptable. Great business model. I urge everyone to keep them on the line for a few minutes.. ask them what the name of the company is. Ask about pricing... get them to go into detail. Eventually numbers will be cleared from their list.
