womanfreebies.com Contacted me that I had won a sweepstakes, wanted me to send western union to receive a receipt to get prize . Internet

While scanning facebook, I was sent a friend request from womanfreebies.com on instant messenger.  I accepted and started a conversation where they informed me I had won the 2015 grand prize sweepstakes.  They said I won 1 million dollars, new car and bonus prizes. 

They stated that they would come to my house by 11:45 the morning of July 21 to award the prizes to me.  They asked for my full name, address and zip code.  Which I gave them still asking them if this was for real.  They said it is 100% legitimate that i won the prizes. 

They then asked that I locate a western union, walmart or money gram to get a claimers receipt to get the confirmation process completed for them to be at my house the next day.  I knew it was a scam then and told them just as I thought, a scam.  They never responded back to me at this statement.
