Like number 202-602-0188 - Robo call says he is David Grey from US Treasury and to call them at this number.  I did that and it was answered by India call center person.  I gave him a piece of my mind for running a scam and then reported the number to US Treasury web site  http://www.treasury.gov/tigta/contact_report_scam.shtml

Got a voicemail from these clowns claiming to be from the US Treasury and informing me of an enforcement action.
Since the US Treasury does not call, but uses the mail, I knew this was a low-life.  Just for the heck of it, I called back and got someone with English as a second language.  I told him to go f**k himself.  I suggest you do likewise; or just ignore these pukes.

Why do they keep calling.  This is crazy.  Can't the phone co. do something about this.

received threatening call from 1-323-729-3661 allegedly from David Gray of US Treasury.  did not call back but wish that i could launch a HellFire missile down the lousy scammers throat.  can someone please help me with that?

Same scenario as above
