This my so-called lottery winnings from some organization associated with the hosting of the 2010 World Cup in South Africa. IDC cost = $1600 more or less.

Answer:
This a well-known scam where you are supposed to pay something first to get a big prize later.

It is a fraud that requires no further action on your part.
SCAM
You're joking, right? Do you not recognise a fraud when you see one?
I hope you're kidding and aren't really taken in by this scam. Do not send any personal information or money to whoever contacted you.
