oh man
I have exactly the same problem!
only my story is even more confusing =(
Fortunejack didn't credit me with the bonus at all!
Fun fact: I checked the maximum bet size and it was fine! I just wanted to bet on an unpopular market and was wondering how much I could bet.
At the same time, I contacted the support chat asking why I was not credited with the already activated bonus. The next day I was credited with part of the bonus. Then I wrote again, and in the end they credited me with the entire bonus. When I tried to place a bet, my limit was also greatly reduced, so there was no way to use the bonus!
In my case, I know for sure that my maximum bet was reduced at the same time as the bonus was awarded! This looks like a bonus scam.

Now I am corresponding with the support service, which tells me that nothing can be done!
But I immediately give them the example that at first you didn’t give me any bonuses at all! Then they added the first part, then another. I currently have two active bonuses that cannot be used.
I immediately asked the support that if you have already divided my bonus into two parts, then you can split it again, into many $2 bonuses, so that I can place bets!
But they told me that nothing could be done!

I keep messaging Fortunejack, but it sounds a lot like a bonus scam! I know for sure that before the bonus was credited, my maximum bet was high! And as soon as the bonus was credited, the maximum bet immediately became very low!
Fortunejack writes that it’s all the provider’s fault! But in this example of mine, I immediately see that the issue can be resolved even now by split the bonus, but Fortunejack refuses to do so! Also, the fact that before the bonus there were no betting limits speaks of casino fraud!
