I tell them I have no ducks.  My elderly Mom is so sick and tired of them bothering her she keeps an airhorn can close by and when they do call, she gives them a shot in the ear.

Got a call from (905) 674-5656 ---no message.Tried calling back---operator came on (recording)--the number is not in service.

I am tired of these callers and do not answer the call, they leave no message so I do not know who they are

They keep calling!  Air duct cleaning...I am doing 2 things now, I am either just hanging up or talking to them without letting them get a word in about a walk I am doing and where the money is going and could they sponsor our team, until they hang up!  Idiots!  Why do we have a do not call list and does anyone actually hire one of these guys who can barely speak English and are usually rude!?!

yes! He has been calling me about 2 times a week. I finally called tigers and they told me how to block numbers online. I did the block and now they call from other numbers. :(. It's annoying

We got a call from this guy, my wife answered and after he said he was calling about duct cleaning, he proceed to ask my wife if she was home alone, and if she was happy. He got told where to go real quick!
