Who called from 3022000972

Does anyone know who calls from this phone number.

Unknown caller from Lewes DE, I did not answer. Caller left automated message about IRS lawsuit. Scam

Caller ID: High S Networks
Called: Aug 3, 2016 at 4:59pm CST
Left automated partial message requesting a call back to "our Department regarding this case against you", then gave 302-200-9072 number. I did not call it. Not sure who it is. Seems fishy.
