I called them back several times and told them they were a a fraud . One guy called me a [***] and one said " I know" when I said they were a fraud. Most of them just hung up on me, this was after one guy said I was going to be arrested in 2 hours !!!!! How nuts !!!!!!

The idiots crossed the wrong person. I am a bit of a geek and can easily locate these  morons .  They better hope the RS gets them before I do !!!

Be careful with that.  Many scam and spam calls look like they are from the US but are really from another country, often one where scamming Americans is not against local law.  They use spoofed numbers to make it look like they are calling from inside the US.
