Facebook Lotto I got Scammed $500. Medford Nationwide

Hello my name is Billy.  I got e message on Facebook from a friend saying I was one of the lucky one to receive $50000.  All I have to do is send $500 by money gram to a certain address and I shall receive my check in seven hours by a Fedex truck.  I believed my friend and sent the money knowing I would receive $50000.  I got a text message from this lady a few hours later saying that the Fedex truck was stopped by the IRS and in order to receive my money I have to pay the IRS there share which was $1500.  But I told the lady that is all the money I have to give her.  That we are not a rich family.  We live by check by check.  The only reason I gave you $500 is that you told me I would be receiving $50000 in seven hours.  I also told her that I would go to the IRS in the morning to see where my money was and how I could get it.  She stated that I should keep this a secret that all IRS companies are different and that she dosen't want to be harrassed by anyone.  She told me she is a Christian women that that was not her thing to talk ugly to people.  I figured out when I told her I was going to go talk to the IRS and for me to keep it a secret something wasn't right.  All I want is my money back or to get this lady in trouble.  I want justice for what she did and doing to everyone else.  She also took $10000 from one of my other friend.  Please let me get justice for what she is doing to everybody.  I worked to hard for my money.  Thanks
