Just got one just now and an Indian speaking person said they were from the United States Federal Grants division. I told them that I am on the DNC list and that they are calling my cell phone and asked them stop calling. He then responded with, "Why is that, Sir?" I said the exact same thing again to him and then he said, "I just want you to know that this is being recorded by the United States Federal Grants division" and then hung up. Such scammers. Now they are claiming to be government officials. You can't report them, because they aren't even based out of this country and use phone numbers created through a call system that can show them calling from anywhere.
I called the FBI before and they pretty much told me that they even get calls, but have no way of tracking them because of the equipment used to make these scams are based out of country and aren't legitimate in any way.
We also ot a call and the guy said his name was Ben Johnson and he gave me a number of 727-378-2733 to call back for the Federal Grants Division. When I called him out on using an American name and sounding Indian he became very irate, and cursing at me. So this happening, I blocked my number, waited a few minutes and called the number he gave me. I then began to give them a rash of hell until they hung up. I then rinsed and repeated.
So take the number above and in times of stress or neding to just flat go off on someone....have some fun with some true POS'.
