Well, the poor guy that just called me got an earful.  2nd call from these guys today, 4th this week - they even called on Easter Monday!  Exactly the same thing happening for us as for everyone else.  Indian sounding accent, unrealistic names.  So annoying!  
I wish there was something we could do that would actually have some effect on this type of thing.  The Do Not Call list sure isn't working.

Duct cleaning at 60% off.... VERY RUDE!!! Thank the Good Lord I'm a Christian woman... if I ever find this guy!!!

They are waiting for an opportune time for you NOT to be at home. That way they can 'case' your home for a possible break-in.The moral of the story is that if anyone wants some service (lawn repair, duct cleaning etc.) then call a reputable company yourself. "Companies" that phone you up are always disreputable, always have excuses and will always rip you off in one manner or another.NEVER give your credit card information to anyone or any company you don't know!

this number called my cell on a weekday before 6pm and theyve also called my house, from a different number i think.....my mom said if they call again, shes going to report them to the fraud department. hopefully that will scare them off

I live in Nepean.They called here Apr.16 @ 12:52PM and hung up when I asked them to put me on their DO-NOT-CALL-LIST.They are VERY RUDE and even though I'm registered on the National DO-NOT-CALL-LIST, I am still getting their calls.

Telemarketer, supposed to be duct cleaning company.  Very annoying.
