11-16-11.  just rang, didn't answer it.

They called both my cell phone (which is a pay as you go!) and my home phone, an hour apart.
Who the hell are these guys?

they just called my cell also

Whoever they are, they seem to think they are above the law. The DO NOT CALL LIST is a joke to them and it seems there not much authority to hold them to it. I got a call from them just now and let it ring. Another company near the same area called the other day.

Same here, didn't answer, didn't leave message.
