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

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

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

called here yesterday- no messagescam or telemarketer given now there are at least 3 of us with same result

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

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