This caller called my home but I did not answer, what do they think that we are all morons like themselves. Do they think by calling us they will get our business. Again I say they people have no character.

From the other site:Got this call saying they are from "air duct cleaning services" --  we get a multitude of calls from these people with a diff number showing up on call display but same South Asian accent voice trying to sell these services. Told them to take my number off their call list but the buggers keep calling back. Will  now just hang up next and every time I hear their intro: "Hi, this is ******** from air duct cleaning services"

I just got a call from these scammers too, but no more!  You're already on the DNC lists in Canada or USA. You've filed the complaint and still they call you, right?You want to know what you can do to stop it... Nothing. You can't. You can only block them. I just added this number to my blocked numbers list.I now have a call-blocking box that works in the USA and Canada that can block up to 200 entries.These can be complete numbers, complete area code exchanges, and even "unknown name & number". Now you too can block such scammers and telemarketers. They call once and you add their number to the box. Now they are blocked. Don't know anyone in a particular area code? Block them all!Want to get one to protect your phone or get one for a friend? $95 + shipping and tax. Need more information? Email me if interested at Call-Blocker @ hotmail.comI promise not to call.

The constant calls from duct cleaning companies has to stop.  How do we do this?

as above.are these people morons?

We consistently, two-three times per day get a call from the same person at "Air Duct Cleaning".  I have asked them several times to remove our number and nothing.  Usually the number does not show up but this number did this time:  (416) 555-9337.  Of course when you call it back...it is not in service, or the call cannot be completed.
