First of all their games are provably fair so you can verify your bets easily, if you think there is something wrong with the bets then prove it.
Hundred of red bets in a row sounds bad but it is something possible especially if you set the game with the highest risk (red) although the chance is quite low.
Can you prove your hundred of red bets in row? It would be nice if you can prove it, but if you cant then I can say that you are bringing baseless accusation.
