Who called from 7203651168

i'm receiving repeated calls and hangups from the number 720-365-1168. my caller ID only identifies this number as a wireless caller

Same here. Finally answered and it was a recording saying the IRS has filed a lawsuit against me. THIS IS A SCAM.

I've been waiting so long.  Waiting and waiting.  I thought there was something wrong with me.  But no, the call has finally come.  The IRS is filing suit against me!  (And this is their final notice.  Maybe that means they won't call anymore!)  Oh Goody!  The IRS!  I've made it to the top of the TeleScammers Golden Call List! Oh, I'm so excited!
