got a call and they left a message telling me to call back. This is a Washington DC area code.  The message sounded like a bad amateur recording. Something about IRS not using a local number.  The recording was bad and I didn't catch the call back number nor did they leave a name.   they also called a week prior from the number 202-754-8461, they also left no name.  I won't answer a number I don't recognize.
