First question: IF you did not recognize the number then why did you answer the phone?   When you do all you have done is to confirm for them that your number is a viable, working number and they WILL  continue to call you, plus sell your number to other scumbags.   Thought for the day:  What IF NO ONE answered their calls?  Would they finally have to give up and go out of business?   Hope so.  PS/ our government's DO NOT CALL list is a joke too.  It works no better than our government does.  Have a great day.

Didn't answer, but based on the above comments, definitely a scam. My car is barely a month old. Warranty fine.

called 4 times stating they wanted my full social number or bank acct number. frauddddd do not answer.

This number called me, said nothing and hung up. I called back and got a recording saying it was a contest to win a bahamas trip sponsored by XM Radio.

Recording saying its a radio station and  I could win a trip to the Bahamas by answering three questions.  Sounds like some form of scam.
