I have asked this company to stop calling for months!. It's always a guy with an Indian accent saying that he is calling from the "Ontario Air Duct Cleaning Company". I told him several times that we are in the "do not call list" , to stop calling! and he just hangs up, but calls again few weeks later. I am reporting them today after months of repeated aggravations.
Though everyone claims this is an air duct cleaning service. All I got was a person repeatedly saying, "hello"... "hello"... in different tones as if we're besties... followed by, "hey man, catch you later"... then he hung up. If they really are calling from Ontario, then they must abide by the DNC list. Otherwise if they are outside Canada, there is nothing the DNC list can do. Often the numbers they call from are not their actual numbers they are calling from.
We could open a case against them if they really are in Canada.
