This IRS scam has become a favorite of our India friends (lol) and Pakistan. They've apparently had some success in scaring people into letting them extort money. Where are the drones when you need one.
New scam number in use based in India. 972-865-8852. Wanted me to send money from a 7-11. I have been calling them 30 times a day and they are screaming mad! If IRS and phone company can't shut them down then torment them.
