Received several calls from this number. There is never any person on the line the times I answer the call. I have registered my number with the do not call registry, but this number still calls.

These people keep calling my home phone.  I've told them at least 5 times to remove me from their list, but they keep calling.  Now they call, wait until I answer and then they hang up.  How do I get them to stop?
They say they are a local contractor.

just got a call from 6611996639, picked up no answer....

This is an number that is Invalid - does not exist; thus it is computer generated and used by scammers. Never give out any information or even acknowledge your name, address, or any financial matters. These people use other false numbers with this same fraud of having a contractor in your area.  BEWARE

I too received a call today, caller ID said "Name Not Found".  The man also said his company name was Superior.  He too said he lived in my local area and asked if we needed any quotes on home repairs.  We also said no.

I received a call from this number. I asked for the business name, address, and phone number. All were phony. I asked the man to stop calling me so he cursed me out and accused me of playing games. He calls frequently.

Said to be a Contractor working in the area with "The Spencers" looking to work for us too. When asked for "The Spencers" address we were advised they lived in a street that is nowhere near us. When my wife pointed this out she was told to "Get your map out and look" Saying this was not professional and not to call again she was told to "F*** off".
