Hello, now we are getting somewhere—you think the Safety Index is inadequately high for Rabona. You have every right to such an opinion.
Since not every complaint is the same and context matters pretty much, I honestly can't say how many unresolved complaints are needed to change the rating. It is never that simple. There are several key aspects—the complaint severity determined by the disputed amount and the fact that such a complaint needs to be closed as unresolved. I hope you see it is not possible to make such a guess.
One unresolved complaint will hardly "do the trick."

Besides, we are unable to use unproven feedback as a fundamental basis for mathematical calculation.
Hence, "taking bonuses away" is actually a customer experience, not a matter for changing the Index. Unpaid winnings—that's another story, yet as I showed you, only once a case ended as unresolved. We are not aware of unpaid players; open complaints may also be resolved.
I suggest you read the guides explaining the process. Are you willing to try? I fear we won't get far without that...
