This number has been part of an extensive fraud against older people in the community. You've won 5 millions dollars from Mega Millions, you need to send money to cover the fees and taxes. The same old thing that has been going on since 2010 across the country. One old victim lost hundreds of thousands of dollars after the fee charges became threats of prosecution by Federal Agents.
Although OLD this scam is taking hundreds of older people to the "poor house." Warn you relatives, neighbors, and friends, "If it sounds to good to be true, it is."
Report all contacts on any of these scams to you state attorney general's office and the local offices of the FBI.
