Do consider maybe getting a call blocking device or phone.. You can google them and many are around $50.00 or so.If its a cell phone, some already have call blocking, if not, there are free apps on the web that will work for some. You can google this. If you have a smart phone, there is a free app called call control. Iphones appear to have apps also. Another one is called Mr. Number.

Threatening call from a "police officer" stating that the reason of call was time sensitive and that I would be in trouble if did not call back.

I got the same threatening call from "IRS Officer" stating that I must return this call or I'll be in truble!

Got the same call from the same number 716 780 4155
