Coin Master complaint: Vikings impossible to complete!!

So I’ve tried completing Vikings quest AGAIN! And it impossible to complete!. Up until the last box I had the same amout of coinsl that I started with and was hitting high bonuses throughout! Get to the last card box and I had about 10 bonuses at x2-x5 which progressed me to about 14% spinning at 25,000 that’s 13 billion spent to get to 14%. I then used nearly all my remaining 3000 spins to try and get coins with then spinning at 25,000 again and only progressed to 37%. Its just impossible to complete. I spend my own money on this game to get spins and counselling to try and complete. I never normally complain but this is getting ridiculous and makes me not want to play anymore at I’m not getting anywhere with it. If I can get my spins back that would be great but would be even better if you could make the games possible to complete.
