Who called from 2063363408

I just got a call from this number to my cell phone.

Automated voice states"...for more information about this case file, please call immediately on our department number 206-336-3408. Thank you."

Since it must be a robocaller because it did not WAIT for the voicemail to begin...BLOCKED!

Wants to come and arrest me. Give me a break!

To inform me that I'm being sued by the IRS

Called twice.  I called back.  Didn't want me, wanted my son.  Started asking questions about him - until I shut them down with  "I know this is a scam & will report you to all the appropriate agencies".
