After 30-40 calls to my home, someone finally had the guts to say anything. The [***] telemarketer had a thick, hasty East Indian accent and rushes through his questions. Here was the word-for-word conversation, and I suggest you follow suit (if you are so lucky to find someone who has the guts to answer the phone on their own call, it took 40 tries in my case), as I have since not had a call in the past week.
Me: Hello? (Pause 3 seconds) Hello? (Pause) Hello? ...about to hang up...
[***]: ...10 seconds later... Are you owner of house?
Me: Yes
[***]: You need duct cleaning.
Me: (Speaking very slowly and clearly). Just had it done. Ducts were cleaned last week. OK for next 10 years.
[***]: You need duct cleaning. We have special 50% off.
Me: I don't need it, I just had the ducts cleaned last week.
[***]: When you have cleaning?
Me: Last week. Don't need cleaning. Take me off your list. Stop calling. I repeat, stop calling.
[***]: Click.
Were you able to get the number from Rogers? I'm on Rogers too. After I had done the *57 thing and asked for the number, the phone company told me they could not give ME the number. I had to file a report to the police and the police would then request this information from the phone company.
Dealing with the police, they told me they would have to phone the phone company for the number, that it was a waste of their resources to be filing a report and that the phone company should give me the number without the police having to get involved.
For the past week, 416-277-1688 'unknown name' has called my Ottawa residence 2-3x a day, usually mid-morning, mid-afternoon then early evening. Line is dead air, followed by a hang-up. Called the number, which is evidently fake, leading to an individual message with no rings and a full message bank.
Has been swiftly reported.
It takes two minutes to report the individual at: https://www.lnnte-dncl.gc.ca/plt-cmp-eng
