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.

Received a call from this number this morning, and an East Indian accented man said he was calling from Ontario Duct Cleaning. I said thanks, not interested. Same number called tonight and when I told another East Indian man that I already told them I wasnt interested, he said, No, No - this is a different caller - that was a different company (Safeway), even though call display showed the exact same number. When I said $150 was too much, he immediately dropped it down to $135, tax included. I told him No thanks, and when he asked why, I said that I didnt trust him , since there was no website, and his phone number came up as unlisted when I called back. He said , no l can  give you a number to call me at, and i told him just to cancel it. after telling him this 4 or 5 times over his protests, I hung up the phone. Very shady!

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.

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.

These guys called yesterday and again today, cant seem to get off their call list.  I have reported to the CRTC multiple times as I am on the do not call list.  I am having the phone company block their numbers.51994817775192563523

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.
