These idiots called my unlisted number.  The first time they called, no one was on the other end so I called the number back.  Got a recording saying I could leave a message and it was forwarding me.  Then I got another recording saying that the voice mail box was full.  The second time, there was a person on the other end.  It's a duct cleaning company.  I told them to remove my number from their list.  We'll see what happens.

Beware they are big time scammers

i know what the heck.....no answer, I am on sick leave so getting no sleep...my husband always askng me too who calling....

I just mess around with all these duct people until they hang up.  I like to pretend they are talking about ducks, and that I have a huge duck problem in my house.  It usually ends with me quacking at them until they hang up.  Once you prove you are a waste of time to them, they usually stop calling.

Just launch a complaint at https://www.lnnte-dncl.gc.ca/plt-cmp-eng if you're registered with the National Do Not Call List.

They have called so many times, Air Duct Cleaning Service...each time I tell them I am on the do not call list and they hang up.  UGH!!!
