Just rabid devil dog telephone terrorists, robo-calling on a tie-line. Part of a vicious circle using (703) & (571) numbers for Northern Virginia, offering a variety of scams and frauds. They call several times every day. Although put in my callblocker weeks ago, they keep calling. The only way to stop all of these robo-callers is to outlaw them, then fine and lock up the telephone company executives that rent them the numbers, thus facilitating the criminal activities, then go after the perps and fine and lock them up. The telephone companies know exactly who the U.S. Agents are, as hey want their monthly fees paid on time every month.
