Challenge them. Think ahead of time as to how you can cuss them out and call them all kinds of vile names and to be able to do it without getting excited or anything.
This is a Nigerian Scam. The guy said that he was with the Government Grants department. The particular department of the government that gives out grants is not going to be knocking on your door or calling your phone.
I quickly told him that he didn't need to call back,, he asked why. I told him that we were not interested in his scam. He said it wasn't a scam and immediately his voice got aggressive and defensive. He then asked me if I was a sheep and called me a very profane person that involves incest. And before I had the chance to respond he hung up.
Think about it folks,, is a government employee going to act like this? I really doubt it.
So now I need to find a porn movie with a lot of loud moaning and screaming and then call him back and hold the phone to the speaker so that he can hear it.
