When you DO get “the” call, be sure you capture the phone number if you have caller ID, and then use one of the following responses as a guide as to what to say:
“Hi, can I please get your phone number in case we get disconnected and I can call you back?” If they do, great! If they don’t, no big deal. Either way let them know you are recording this call and will be reporting them (and the number if they give it to you) to the Federal Authorities as you know this is a scam. At this point you will hear the distinct sound of being hung up on.
The other option you can try is… "Hi, I’m sorry to hear you are involved in such an illegal enterprise. Can I pray for you? Where are you located? My local (church/synagogue/mosk) has many outreach programs and I am sure we can help you turn your life around.”
Alright, this option is a little tongue-in-cheek, but at least it’s light hearted and sends the proper message that you are on to them resulting in them ending the call.
