Who called from 2012056392

This number calls me several times a day and when I answer there is nobody there.  Today they called at 6:50 AM.  Really?  During the Christmas holiday calling at that hour is inexcusable.  I am on the Do Not Call list and do not have any outstanding debts.

They called here too and only music played for like 2 mins without any answer...

Questioned this caller and told them not to call anymore.  Guy told me to shut up and he wanted to kill me.  Not too impressed.

call numerous times a day been told to stop for months.  I have filed many complaints.  They say they are calling because of a medical liability case.

I get many calls from this number - only silence when I answer.
