Dream11 Fantasy — fake teams from dream 11 in gl contest

I can see that the winners of grand leagues they are played only less than 10 contest before, who has no idea about this game, and 0 contest played teams are won today in all grand leagues. One of the team name got changed after the match and application itself showing as "user changed the team name after joining contest". I believe it is not possible according to dream 11 rules. The thing is i have complete pdf copy of all team names with payers they selected. I took this very beginning of the match.. After match finishes dream 11 manipulated the pdf also. I have both pdf copies and sure i'm gonna put case on this # company. Dream 11 doing cheating only for big grand leagues!!!
