Terrible payouts and lack of bonus

I have been playing this casino for some time now. I have had a few payouts here and there some big and some small. But the chances of actually winning is terrible. When you play big bets, boom!, money gone. Not even a credit in return. Then you go and bet R1 and get the most amazing spins. (Small payout though)

If it goes on like this I will most probably stop playing in general. Not even offered a free bonus or anything with the amount of money I have deposited.

I am extremely disappointed in my experience.
