Efrag has been in the business of Counter-Strike for a long time. Being one of the premier event organisers a few years ago, they were hosting and organising tournaments. However, it seems they were unable to pay up for their winners. The prize money owed to the players from almost 2 years ago, still remains unpaid to the teams.
