My son in Fort Lauderdale, Fl. just received a call from these maggots...saying federal marshalls would be arresting him within two hours if he didn't respond immediately with an out-of-court $5,000 delinquent tax settlement. Scared him to death, initially, until the caller (Indian) started requesting personal information. At that point, he hung up. A-holes who deserve, and richly so, a bullet to the brain.
Got a call from +1 (360) 226-0034. Said they were the IRS investigations. I just hung up. Far as I know I'm paid up on all my taxes. Pretty sure it's a scam.
