Just do what I do when I get unwanted scam calls.
Start having phone sex with whoever is on the other line.
"Hello sir, we are calling to let you know, you have won an all expenses paid cruise to Koreikstan!"
"I am glad you called. I have a fistful of c@*k, and I really want someone to hear me make a map of Hawaii all over my belly... grunt, sigh.."
