Got a call from this number, so I called them back, and I played along.  Ask if I had a lawyer, I said and provided with a fake name.  He hang up on me.  So I called again, asking why he hanged up, he hang up again.  So I called again, he block my number.  So I use another number and called again, gave my name, etc...  he hang up again, So I called again, using the same number, he block that number too... I did it several times with different number, same result... he block it...  till i next time...
