The Sweepstake Audit Bureau claimed that I should mail 5 dollars in order to receive unclaimed funds Dallas, Texas

I received a document from the Sweepstake Audit Bureau stating that my immediate attention and response was needed so as not to forfeit the right to win 12,000,000 dollars. I was asked to mail in a "one time research and data fee" of 5 dollars. Failure to mail in the money and claim form would result in loss of eligibility. I am outraged by this company and others like them who prey on the general public, especially those who are lower middle class and the poor. They know people are experiencing financial woes and that they would probably be able to mail in 5 dollars...especially to secure a large check.  This is so wrong on many levels. I pray they can be stopped....Just think of all the 5 dollars payments they have received from the unsuspecting public.
