They called telling my grandmother thaty she won 775,000 and in order to get the money she had to send in 1,700! i stoped my granny right there and i tried to call the man back and the call would not go through, and also i asked to speak to a superviser the first time he called he said i am the head federal agent. He did provide an bank account number that of course i had no way to varify it! so be carefull i feel its a scam.
