I am in the same boat as the gentleman above.  Said yes, for a specific appointment, but the call dropped.  Tried to call back but just got high pitched beep.  Now I'm afraid to decline when he arrives at the door.  Maybe I'll just call the police and see if they will come to the house at that time.

Good luck John

I just got called from Josh at Adam's trying to sell duct cleaning. Reminded him that he was calling a no call nymber. he say's he doesn't care...go ahead and report him. And yes, the guy has an east indian voice.......

Hi guys, this number called me over a year ago offering a duct cleaning, so I made an appointment with them because they are offering me a good deal, imagine 50% off. So I search on the web and found out that the company that he was trying to tell me is not existing at all, so when he made a call for confirmation, I cancelled the schedule, and told them that I will call them back when I'm ready. Last week, I received another call from this number again, this time I told myself that I would give it a try! So I made a specific appointment. To cut the story short, they have send me a legal company to work for my duct cleaning, and I must say they did the job well for only $99. Duct cleaning doesn't have to be complicated, and I think $99 is just a fair price.

Ive been getting these calls for like a year now. and all they do is harrarss me and my sisters. its very annoying i swear it sounds like and indian guy. ive told them to take me off their list, and give it to the manager in return i get an answer either "oh by the way i am the manager" or "oh my manager is very busy but if he was free i would tell him to talk to you". then starts swearing and calling back, ive cussed a handful at him aswell, in hindi aswell so atleast the non english speaking bastard could understand. this is very annoying i dont know what to do. do the police actually do anythign about it?? the last time my mom answered the phone, and hes like, oh was it you who answered the phone 5 minutes ago with the nice voie, and has no respect what so ever for other ppl. i would like to use his head as a duct cleaner. s**t!!
