This caller also tried to sell me on his Dust cleaning service. Trouble is I am on the National Do Not Call List  and he violated their terms. I filed a formal complaint against him.

Claim they are a carpet/furnace cleaning outfit

I was housesitting at my parents home & he asked if I would like the price of the furnace cleaning special. I said no thank you, you'll have to call back next week. He then proceeded to ask why. I told him I was not the home owner and he'd need to call back. He said... "What is your name?" I said, Why do you need to konw my name. He mumbled something and I asked him to repeat what he said. I again told him that he did not need to know my name. He said, "I need to know your name as I'm crazy about your voice."
What a creep... I was ready to call the cops and may still...

Just got 7 consecutive calls from this number and nothing on the other end when I picked up.

A person called from this number to our housenumber, claiming that we had been calling him for three days and that he was going to call the cops.....etc. This was a very strange call. We never called the number, so I don't know where this comes from.
