My only suggestion would be to file a BBB complaint against them. Looks like over forty people have in the last three years.
Here is the link worldwinner BBB site. http://reports-boston.bbb.org/...One negative example of this shady company is they put your winnings on 1099 form each year. Then me for example, I won ten thousand in tournaments, however it cost me twelve thousand dollars to make that ten thousand, thus a two thousand dollar loss right? Not according to them, I can't write the twelve thousand dollars in gambling losses because the site states it is a game of skill not gambling.
Please beware and don't be like me!!
Monetary Loss: $2000.
