Unfortunately, I have complained to CRTC twice already and have just put in a third. I'm thinking they must be calling from out of country and don't have to comply.
I get calls several times a week from a company claiming to be Air Duct Cleaning Services and they give this number as their contact info. when you call that number it says mailbox full. they hang up on you when you ask them about this.
Calls at least 5 times per week, nothing gets rid of them so I tell them I would like to use them but can't afford it . I waste about 10 minutes a day telling them a crap story.
