I too  have calls coming all the time and Im on the DNC list since day one.
They need to be shut down

It's a telemarketing company for Fresh Air Duct Cleaning.  If we all report it to the DNCL it may slow them down. https://www.lnnte-dncl.gc.ca/plt-cmp-eng

They just called same, supervisor took the phone to close the deal, blocked number but confirmed same company Fresh Air Duct cleaning.   I went to their website and confirmed their contact information.  
I have reported them to crtc as well.

these guys are still making calls.how come we can't get them shut down WTF!!!!!!!!

Got a call from this number asking if I had a Visa card, and when I said yes, told me I was a valued rewards customer and I had won a prize holiday to the U.S. At this point I immediately hung up. Would be very concerned that if it was my wife she wouldn't catch on to this, and if they asked her to confirm her credit card number would give it out.
