Lol...so now he is a federal agent who is calling because I commited internet fradulant withbhis mother. Oh god what a crap. An indian voice with name Peter Brown thank God its not John Smith. Not worth the time.
Do not answer calls from people you do not know, if it's official your get a letter and a message which you can later verify at the post office as being fraud or not. Saves you stress and time.
