Complaint Review: Oportunities Unlimited Publications Inc. (OPP)

I live in Ireland, and my brother who is mentally ill received this rubbish, but very formal looking express green envelope with two impressive documents saying he had won 15,000 Euro, signed by John Winstead, Thomas Moore, and Mitchell Wagner. He wants to send off 15 Euro, which they are asking for along with the answer to a math question about halving the winnings.  These people are scamming the most vulnerable in our society, who believe they will get money from nothing. We all have to put a stop to this. I wonder who is investigating these blatant thieves?? Hoping this prevents someone else becoming a victim as my brother almost did. Dont give up on dreams, but truly if it sounds too good to be true, then it is, and as I said to my brother, if they could send you these documents for free, surely they could also send the 'winning money' for free also. think people!!
