Consider maybe getting a call blocking device or phone.. You can google them and many are around $60.00 or so.

Left no message. Found this site. Thank you! Will not answer ANY calls from a 202 area code

did not answer

Hi, im from Holland and i get those calls too, dont know what to do with it.
Just ignore them, or what?

This number has called several times today but only lets the phone ring twice so you do not have time to answer. I called their number but did not get a response. A good thing as they would not like what I have to say. Since I am on the no call list I should be able to sue each time they call.
