I got a message from the same number: (905) 874-2030. they identified as Frontline Home Services and called about Duct cleaning. My number is supposedly on the CRTC no not call list. This company  needs to stop harassing people.

This company has been harassing us for almost a year. We have tried everything from being polite to threatening and nothing seems to work. I want them stopped and shut down!

Get this, everytime it's the same person and the person keeps giving different names. The last I heard of him, he said his name was Johnny Bravo. Had a good laugh at that one. They haven't called us ever since my brother spoke to him. I guess a firm voice shuts him up.

Getting calls 3 times a day. Telemarketing for Front Line Home Services.  I am on the Do Not Call List.

File a complaint with CRTC website. These duct cleaners routinely thumb their noses at the do not call list even when they've been fined in the past. I'd like to run some soot up their own individual ducts!
