Hung up on my answering machine. Googled them -- this is a number for KLJ Field Services out of Windsor, Nova Scotia, Canada. They do consumer research marketing by telephone. They generate phone numbers at random to pester and don't even bother to check and see if they're calling a cell phone or a number that is on the federal or a state's DO NOT CALL LIST, like mine. They have a website with a FAQ page and an opt-out form where you can request they put you on their very own do not call list. Yeah, like that will really make them stop calling. They've called my house dozens of times over the past two months.
