Am getting repeated calls from this duct cleaning firm despite being on the do not call list

Got another call at 8:13 p.m. 24/4/13.   First call was on 17/04/13Display screen says "unknown name". I didn't answer it -- as it was an unfamiliar number,so had to be a telemarketer. :(

Duct cleaning...so they claim.  I've played around enough with them...now I have a whistle handy for the next time.

two calls today! 613 area code but long distance ring I live in the 613 area code so it shouldn't be a long distance call. And you can't use call block says number is not available. Will give them heck next time and will report them is they call again

It is the AWFUL duct cleaning scam people AGAIN!!!  They call us several times a day.

Whoever they are - they called here mid afternoon.  They left no message.  Very annoying!!
