Anyone know how to stop this guy auto calling? We're in do not call list and this guy keep calling me. Really annoying.

tired of getting this call...5 times a week from this numer

STOP CALLING MY HOME11111

It's not an actual duct cleaning company, so for the guy who was happy with the service, you got lucky.
This is how it works.
They have an autodialer and spoofed numbers (there is no way to ever call them back).
The autodialer is why there is a delay with speaking to someone, as it only transferes to a live person if someone answers on the other end.
If they sell a job, it is farmed out on freelancer.ca to the lowest bidder.  You may get a respectable guy to clean your ducts, maybe not, but the guys that sell it to you are total scum.

i got a call from my friend who gave my number and it is a duct cleaning company
i dont know how they got my friends number or name.

Its duct.cleaning, gave a good price and did a good job, but they do call too often.

Received a call from this number.  The person knew my name but was disconnected on their end.  Sounded like a crank call.

I don't want calls from this number. DO NOT CALL LISTING.

This number has called during the day when we are at work and also at night, but there's no one speaking.  When you call the number back, it just rings and then slips into a busy signal.  The call last night I answered sounded like a conference call and an automated message said something about being added to the call.  I have since added this number to my screening list with my Bell Call Privacy service.  It was accepted and now they will not be able to call back.

I keep getting no matter how many times I ask not to call from an air duct company.  I have no air ducts I have problems breathing and getting to the phone.  They will not stop calling.  These same telemarketers I beleive recently changed or added telephone directory numbers.

Air duct cleaning company.  Not sure if its legitimate or spoofing the telephone number.  Calls daily
