female with foreign accent and terrible garbled phone wanted to set up a time where they could come by and give a free inspection of the roof. I asked her "how did you get this number?" she answered that they have "the number in their database" (dah).
Told her to "get the number out of their database &!%(# ".... and hung up on the SCAMMER.

Same thing.  Second time they have called in a couple of months.  I had already informed them our # is on the Do Not Call List.  They said they would remove it.  Obviously did not.  I was able to get him to tell me who he worked for.  At first he said the company was in India.  I said not with the accent he had.  I looked up the company he was calling on behalf of, and called them (for the second time in a couple months).  The owner defended the practice.  I'm reporting to FCC, FTC and MN Attorney General's office.  One nice thing about MN is that only one person has to know a phone call is being recorded.  I have them recorded.  The amount of paper work he will face should be remarkable, not to mention the time he will have to spend.  And if they prosecute him, add the costs of an attorney.  I'm tired of these clowns thinking they can get over.  Who in their right mind uses tactics that tick off people.  There are so many legitimate ways to advertise.
If they call you, they will give you the name of the exterior construction company automatically.  Then just look it up on google and whitepages.

5/6/16 - ID is UNAVAILABLE.  I did not answer, did not recognize number, they did not leave a message.

They have called 3 times today and at least twice yesterday.  Have not answered because I know the number is a scam call.
