I had to speak first after they called me.  A man spoke with a heavy accent.  I told him to repeat himself and I understood "duct cleaning" and very little else. I hung up.

Stop calling

update...The number they gave me was to someone who knew nothing of this scam, the gentleman who returned my call had no idea about this duct cleaning telemarketing scam and he seemed quite honest. It would appear they just gave me a random number.

Me again, this time i got a call from them under private number. I played along and asked for a contact number to give my friends because they might be interested. they gave me this number: 416-694-7597.  I called the number while still on the phone with them and i reached a voicemail with no description. I then told them that their number did not work and i asked to speak to a supervisor. Then supervisor Henry came on the line and push harder for my info and denying me any more of their info..such an obvious scam. Lets all call Bell and complain, see if we cant get some lawsuit going, this is harassment, I always get these calls! Who's with me?

Hey. You'd think that maybe Bell Canada would do something about it, but the fact is they don't give a f****ng s*** as long as they're making money.

Saturday morning 9:30am I got a call from this number waking me up,I did not recognize it so I let it go. They left no message and when I tired calling back it said the number was not in service. Any way of finding out who it is and where they are?

We received a call tonight offering Duct Cleaning.  We advised them of our Do Not Call Statu and that they keep calling us.  We asked that they not call again.  
We were told to F**K OFF!
Tried calling back the "Unkown Name" number.  Bell identifies it as a number not assigned.  My query is how can a company (Rip off scheme) be able to use an unassigned number?  Where else can this be reported to get it to stop?

The Caller did not Identify their company.

annoying calls 3/5 times per week with other phone numbers displayed. duct leaning.

Duct cleaning A**HOLES. Have been calling for months they've been told not to call again and to remove
my number off their list. clonk hang up.

go get a real job

Just got a call from this number as well for air duct cleaning services. Am about to make my number unlisted due to the high volume of calls from this scam company.

Didn't answer but now I'm glad I didn't! Would have told them I was a 9-1-1 dispatcher and I deal with real emergencies, not duct cleaning ones (I am NOT a dispatcher in real life by the way, I'm just planning on saying that to shut them up).....WARNING: THESE GUYS WILL STOP AT NOTHING.  THEY WILL MAKE IT SEEM LIKE A REGULAR PHONE NUMBER TO GET YOU TO PICK UP.....AND THEY WILL CALL AT REALLY UNREASONABLE TIMES.....I GOT A CALL 5 DAYS AGO FROM A DIFFERENT PHONE NUMBER.  THE WOMAN WHO ANSWERED WAS SO HEAVILY ACCENTED IT LITERALLY SOUNDED LIKE SHE WAS HIGH......THEY'VE ALSO CALLED AT LIKE 7 IN THE MORNING ON A SATURDAY!  GIVE ME A FREAKING BREAK!  WE DO NOT WANT YOUR SERVICES, GET OVER IT!

Another one of those calls where I pick up and say hello, then they say hello.  Don't people understand once I say hello you should speak first?

Duct Cleaning Scam

Go f*** yourselves.  Worthless c***sucking pigs.

They are not thieves looking to break in, they want a credit card number to arrange an appointment and they will bleed that credit card dry.

You mean duct cleaning right?

i wish these people would stop calling my house! LEAVE ME ALONE!!!

keep calling about duct cleaning, but could be anything, can be thieves that recording the info of places to  brake-into homes/apartments etc. I got too many calls and from different phone numbers as i keep blocking them and then come back again from different number. I WILL TRY TO LOCATE THE PHYSICAL ADDRESS
AND FIX 'EM PERMANENTLY.

Number on phone is 44416-724-0020.  Got a call Nov 26 from someone claiming to represent Paramount Heating in Toronto. Got to  supervisor "Terry". Asked for a call back number but they said they don't have one. Said they are calling from the promotions department and it's a short term promotion. Sounded like a call center...lots of background noise and static line. "Terry" sounded like he was calling from India or Sri Lanka.  Told them last week they were Front Line Home Services and this week Paramount Heating Services, and what would they be next week?  They told me they would be F**k your mother Home Services and they hung up.
