These people keep calling me saying they r the police

These say their the irs

Keep getting calls from this #. I do not answer. They leave threatening voice mail. How do I stop it?

Keeps calling with an automated message to call or have my lawyer call them back. IRS problems or something.

I've been receiving calls from this # 360-851-1341 saying they are officer Webster. I returned the call and spoke to Marvin Black, by the way couldn't speak english, saying I owe the IRS and the police will be serving me papers. I told him it wasn't possible and I have my tax returns in hand. I told him to send me proper documents and hung up. I then tracked down where the call came from and then found out its a scams.
