Scam! This is big time IRS Scam

Caller kept calling to say he is going to kill all my family and that i should send him 3000 dollars. Caller name himself David and he calls from california

Got a call from this number as a follow up IRS scam call. The person introduced himself as an FBI agent. When I told him that I am going to report him right away , he hung up.

Heavy Jamaican accent.  American Cash Awards.  Keep calling my home phone about me winning a Mercedes and $3million . Wants me to pay $205.00 prior to SOMEONE arriving today at my door with the check to take me to the my bank. A bunch of bologna.

Told me I won millions of dollars, I just have send him $4,299 first. Obvious, lame scam
