Coin Master complaint: Ridiculous Viking Quest Mission

I started this game few months ago and have been trying the Viking Quest Mission. I found it is difficult to complete. Last Viking Quest, I found it had some changes and it is quite easy to get wheel bonus, maybe 3 wheel bonus spins out of 50 spins, but today I found that it is totally ridiculous to complete. I used 100B coins in my final mission which requires me to win 13.75B on wheel bonus but to my surprise and disappointment, I only managed to get 2 wheel bonus spins!!! I should have used the 100B building my village instead of playing this ridiculous mission. I have spent almost RM7k in this game up to date. On average you can see that I may end up with 142 spins (highest bet 700mill per bet) but only managed to get 2 wheel bonus spins??? How does this make any sense!!! I will not spend a penny on this game anymore if no actions taken. I had made a complaint on complain.biz
