Coin Master complaint: System failed to give rewards

I play coin Master Faithfully during the Viking Quest I usually only try to go up to the first gold card reward but sometimes I will go further I made it up to the second to last reward before the big gold card reward and I was betting 80 million Atlanta on bonus wheel and it was 50 which should have resulted into giving me four billion coins which would have filled up the remaining part of the meter taking me to the next reward stage but instead of giving me my coins the game completely shut down and then restarted going back to Viking my meter did not move at all and I did not receive the coins coinmaster makes it hard enough to be able to receive cards that are needed even when you level up I really would like this matter fixed I know it’s just a game but however when you put as much time as you do into some of these games keeping your Islands built and everything and then have the game cheat you like this it becomes an issue
