I answer they hang up.

Rude language and hang-up when asked for contact information to call the soliciter back, and repeated calls soliciting me, despite repeated efforts to stop the calls.

Me too!  I've been advised to report them to abuse@level3.com, I suspect the junk & solicitation phone calls I get repeatedly are somehow connected to / or got my info from one of the service providers I PAY! DirecTV, Comcast, Vonage, or Verizon...this better not be the truth.

called asked if i had owed back taxes at the federal or state level..did not give me an option to opt out.
