Call almost every day.  I am no longer polite with them and they still call.

The do not call registry is a joke.  Still get all sorts of unwanted calls.

A good way is to tell them that you have geese, not ducks and ask if they can clean your backyard and roof.

why they call us too many time

When these people call about cleaning my ducts I reply that we don't have ducks or geese for that matter.  Usually gets a pause and silence from them.  I will have to try the quacking next time that someone suggested in a previous note.  I thought that was cute.

These "Duct Cleaners" have been calling me every couple of days for several weeks. I started out very calm and polite. Told them my ducts were just cleaned - they hung up. Told them Asked to be taken off of their call list - they hung up. I'm sure the stories are all the same. Decided to tell them that I am busy at the moment but would like to call them back to discuss - asking them for a company name and phone number - which of course they won't give... they would prefer to call back. They told me the name of the company is "Duct Cleaning Company". haha. Now they swear at me. Good grief.

The hang ups were annoying... the filthy language unacceptable. Great business model.

I urge everyone to keep them on the line for a few minutes.. ask them what the name of the company is. Ask about pricing... get them to go into detail. Eventually numbers will be cleared from their list.

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.
