I get calls from these f****rs too. Although when you call them back, even though they don't answer they have a voice mail. LOL! So I left them bout a million messages ranting on and on and pretending to be a pissed off Chinese take out delivery boy prostitute. lololol VERY amusing. Lesson to these harassing callers, don't f*** with me.

phone calls with no one on line when picked up. STOP IT

My cell phone call display showed a very long nonsense number. i didn't answer that of course. Yet, the call log registered this (416) no. I took your advice.
I phoned and said I needed specific company info to forward to my lawyer. I suggested that I was going to seek a class action suit.
"Four Seasons...a duct cleaning company."

He's been calling my house too!  I will report him the next time he calls and you guys should as well.

I received a call from them last nite @ 8:45 p.m. - some guy identified himself (I only really heard his last name "phuong" another  telemarketer who can't  speak English - I have many other calls from telemarketers & have found out these callers are from Bell Canada & blasted several people until I reached someone who finally & hopefully removed my name from their lists - the most famous # to call & harrass me is from 000-000-0000 - I reported this to Bell & eventually these calls stopped from this number also although they did call here again about a month agoI asked their name, supervisor's name & what country they are calling from as I will be forwarding their names to my lawyer as I will be filing harrassment charges again them - that puts them in sheer panic mode & they hang up

These yahoos are calling about air duct cleaning services.  If you ask them to remove your number, they either hang up on you or they assure you that they will remove the number.  I've asked a dozen times and am still being called.  If you ask for a manager - they hang up on you.  I will be filing a complaint with the CRTC and I suggest everyone else do the same.
