This "idiot" called me this morning at 5:30 am. If you answer, he says in the same monatone voice. "sorry, wrong number" This is my 4th or 5th call from him. And I am on the 'do not call list'. I will be reporting it today.
Also, When you call it back, the operator says, sorry you have dialed an incorrect number. He must have someway of changing the number his phone puts out to caller ID. which means no way to catch him.
