Got a call from them when  I was out.

Extended Car Warranty telemarketing scam.  They will ignore you if you ask to be placed on a Do Not Call list.  If you press 1 to talk to a rep, sometimes you can get through far enough to see where the call is actually originating.

called a few times in quick succession.

this # called me but didnt say anything?  I caklled it back and it said "the caller you are trying to reach si not availible, please leave a message"..but i didnt leave one.
