I get calls everyday to my home office number from this number. Caller ID comes up NAD. months ago they said they where automobile extended warranty company for Toyota. Toyota has there own not this scam company. I told them to take me off their list, but constantly call. This time I answered and immediately, when I could here a voice, I told him to take me off their F&^*ing list. I told him I have told them before. He started telling ME to shut up and kept interrupting my saying you shut when I kept repeating to take me off their list. So, just don't answer when the Caller ID says NAD because they won't listen and are trying to find a sucker to scam.
