I am receiving these same calls from these people......they are leaving threatening messages on my phone. They really need to be stopped, they are calling me from 2 different number 3476191465 & 3476741362.
Your welcome and consider maybe getting a call blocking device or phone.. You can google them and many are around $60.00 or so. That will slow them down anyway. But keep in mind, they change numbers so buy one that has a lot of blocking ability and maybe will cover area codes as well. Also make sure if its email, to block them and/or attach it to a complaint with IC3, the cyber crimes division of the FBI.
