they called me from a 780 area code the other day, now from this number. I got that I was specially chosen for a prize, press 1 to accept.. blah blah....
scam

when i called it back the machine says "you have reached the DNC request line. please enter your number to be added"..... SCAM.

I have received phone calls from this number as well.
Thank you for your posts.
No message was left on my answering machine. Usually that means that it IS a scam.

It's a marketing agency in London, with their apparent DNC line in California. They call after your local dealership has handed out your information to anyone they feel like so they call repeatedly call with car info, survey, or unnecessary service reminders. I would call the dealer you bought the used car from, or car shop you had work done at and let them have it for giving out your number.

I found a good way to deal with these idiots.  I leave my fax machine on.  I can see who is calling and if I don't answer the phone quickly the harassers get a nice screech in their ears.
