BIG RIPOFF/BIG WIN WONT DOWNLOAD COINS

I havent purchased any coins, just rely on watching videos to replace money lost. Twice in ten minutes after a big win, app locked up. Did this before. I had to turnoff/on phone to play again. lost all the money. You cant tell me they arent doing this on purpose so I buy their coins
