Hi and thanks for the follow-up. I believe you when you say a bonus buy is not possible with bonus funds; to me, it makes sense too.
Here's the idea though: if you still can access your casino account, can you take a look at the gaming history, if it's even there, of course? In my opinion, such a situation could be cleared by checking those problematic spins in the history. The balance, bet and outcome should be there.
However, not every platform allows players such a detailed history, so that's just an idea... I would not be surprised to see this request in the complaint thread, though.
Now that I am giving it a second try, could it be possible that the bet is not the only problem? I mean, the description the casino sent you is not explicitly specific, I'd say.
Are there any other parts explaining how the fair play was breached? Perhaps I didnt understand it well at all. 🙁
