Don't know for sure IF they meant to do a prank call or someone was busy on noisy machine not hearing my hello. Twice and stayed on at least fifteen minutes each time. Suspicious call.

I have received a call from the same number last week. They offered me Duct Cleaning of my house and I agreed just to see who they are? Just got the services from them and they did a fantastic job and were not at all a scam.

Then you must be a friend of theirs.  Check out (905) 342-1223 and (416) 800-0798   They are all the same people, Tamils waiting to break into your house.

They call all the time. I have asked them to take me off the list but to no avail. I have also asked them what the company name is and also was hung up on. Just got a call 5 min ago and they didn't even answer. This needs to be stopped...so annoying! Any ideas?

Mine came today (March 29/12) and it was a long distance ring, even though (416) 252-4366 is NOT LD from where I am.  Its a spoofed number out of their KSU/PBX coming from a call center most likely offshore.Pick up receiver, let sit on desk.  They pay minimum 6 seconds, maybe more, so it costs them.

A guy called to ask for the home owner, then he began to sell "Duct cleaning".  Even though you reject his request, he still calls you again.

If you pick up the phone, they will call you bi-weekly and asked for the same question. If you don't pick up the phone, they will call you everyday.

what an idiot...people like this are the ones that keep these scam artists in business...they probably used a household vacuum to do the job - he would not know the difference!!!
