I got the call. Very heavily accented man asked to speak to...some one.... couldnt understand. When I said wrong number he said 'no no duct cleaning we have a deal' I told him we are happy with our dirty ducts and hung up.

these air duct cleaning people are calling me 2-3x daily.  Tried everything to get rid of them.   Now I just screw around with the guy until he realizes I'm screwing with him........I suspect they are spoofing local numbers.  I add the number to call screen but they just call from a new number the next day.

Oriental male person who I could not understand. Very loud. I asked to be taken off his list and he hung up. Who is it?

This number called me twice today. Couldn't a understand the first man at all. He was extremely rude when I finally understood enough to know that he was was calling about a cleaning sevice. Then an hour later, same number different man called back and I said that this number had already called today and he hung up on me.

It's one of those off shore scams for duct cleaning.  They are spoofing local numbers now so we'll answer.  When these duct cleaning companies call I tell them I don't have ducks I have geese... they don't know what to say.  Lol  I have also asked them to hold on a minute only to not return to the phone until they hang up.  My next move is to get a blow horn.  Lol

I too received 2 calls on March 24 and then again today.  I have reported them twice to CRTC.  My next step will be to blow my whistle into the phone and destroy their eardrums.  It worked with the supposed "you have a problem with Windows and you need our help" .  Or it could have been that I told them I had a Mac.  Maybe tell them you have electric wall heat.
