They called today. After I said "hello" 3 times I was patched into the call center where you hear the background noise of others making calls. I then said "Hello A1 duct cleaning, how can I help you today?" and they hung up on me!

I found this number on my caller ID from a call I missed this morning, - didn't recognize it and just looked it up.  Thanks for posting your call.  Clever response too. ;)

They called at one o'clock, identified themselves as duct cleaning. I asked them to take me off their list, I waited fora response, got none, said are you still there, no answer. I also received a called from another similar number on 12/28 at 2:30pm.
