These idiots call every night a few times, they leave no message and when you answer they hang up on you.
I looked on their website and called that number in Idaho,  208.232.1818.
There's an option to press 8 to be removed from their call lists. I was transferred to someone's voicemail who just got a nasty voicemail telling him to remove me from their call list.
Hopefully this helps but I'm not counting on it. I suggest everyone bombard this morons voicemail box!

Got three calls tonight.  First time let it go to answering machine; no message left. Second time answered and no one.  Third time let it go to answering machine; no message.  Called it back from a secure cell phone and it comes up, "This number is not in service at this time;  31005."

They've called two more times since and I've called that morons voicemail two more times. It's going to be very full....

At least a dozen calls in the few days, caller ID sometimes says Research Center, sometimes says Roseville MI

I have been receiving 2-3 calls a day for the last week.  Tonight the first was at 8pm and the last was 9:25pm.  I almost answered the last to give them a piece of my mind but instead just picked up and hung up.  This is really getting old!!
