Who called from 2024560000

They have called me 4--yes, FOUR!--times today in less than 7 hours! Did not answer any of their calls as I don't answer calls outside of my area code. Like everyone else, they didn't leave any message; just keep calling & calling in the hopes that I'll finally answer. Wonder how long it will take them to figure out I ain't answering?.........

They call constantly and ask for my husband who died over a year ago. When I tell them he's dead they abruptly hang up

Same as the above.  I get one per day for the last 3 days.  Caller never says anything.  Wonder if they will respond to a female voice...

Nope. I'm a chick, and they never respond. I got 3 calls in 3 hours, and no one ever answers when I say hello. Last one I told them to stop calling. Next time: I'm blowing my air horn into the phone.

I get a call per day from this number.  caller never speaks, just hangs up.  202-456-0000
