Got the same call this morning 11/12/14 saying to call 202-464-2549. My phone log shows it came from 934-561-3641. A call yesterday also that showed a Seattle number 253-204-7575 and there was a person on the phone with an accent that was barely understandable. Today an automated call telling me I must call this Washington DC number or I would be sued. I will report this today as mentioned in this article.
(I hope they call again at a time when I can answer with no one else within ear shot. They will get some very understandable English words.)
Called a number back 253 204-7575 and an individual answered with a thick middle eastern accent. I told him I hope he gets hit by a bus and lives the remainder of his life as a parapalegic drinking out of a straw. He proceeded, to threaten me "watch who you're talking to [***], I'll find you." Good stuff.
Got the call 2 minutes ago from number 931-562-3651 and ask to call back at 202-464-2549. googled the number I this is the first page I land. So glad there are site like this to generates high hit on search engines.
