why they call us too many time

I have received 7 calls from this number in less than 24 hours.  The person is rude when I say, "No, thank you." and hangs up on me.  After the first call, I keep getting calls where no one speaks or I am forwarded to another number as though I made a call.

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!!!

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.

I just had these people call and ask for the home owners. When I said they were not available they and asked to take a message they replied with "This must be their lovely daughter". I replied with "yes, can I ask why you are calling?" and the response I got was "What's your name? I'm calling because I really like you". This number continually calls my house and either there is no one on the other line or they get angry and rude when I say I am not interested in their services. Can something be done about this so that they stop calling? I'm getting very annoyed by the calls.

I just like to mess with them now. They call every day and I even told them NO stop calling but they dont seem to document anything and someone else or the same guy calls back later forgetting he called me already..Heres a tip, act dumb. and be like What? Ducks? I dont have any Ducks? Why do you want to clean my Duck?Hahahah that just confuses them its fun try it!
